Description

  The present invention relates to a package component that accommodates an optical waveguide assembly including an optical waveguide device that outputs an optical signal input to an input end to an output end, and a method for manufacturing the same.

  In a packaged part containing an arrayed optical waveguide device and fiber array assembly, that is, an optical waveguide assembly, the holding part holding the optical element, the adhesive, etc. expands and contracts as the temperature of the installation environment changes. It is known that the stress change is transmitted to the optical waveguide connected to the waveguide coupled body itself or the optical waveguide coupled body. As a result, the stress change is transmitted to the optical waveguide coupling body or the optical fiber positioned in the package component, thereby increasing the fluctuation amount of the optical characteristics, for example, the power (intensity) of the transmitted optical signal (light). .

In addition, in order to absorb the difference in the linear expansion coefficient of the member to be used, by filling the resin in the case housing the optical waveguide combined body, the stress when the resin of other parts contracts is filled in the case. There is a proposal to absorb with a resin (for example, see Patent Document 1).

  ADVANTAGE OF THE INVENTION According to this invention, the package component which accommodated the optical-waveguide coupling body which can suppress the change of the optical characteristic accompanying environmental change, ensuring a mechanical strength, and its manufacturing method are provided.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a schematic diagram for explaining an example of a package component to which an embodiment of the present invention is applied and which accommodates an optical element, for example, an optical waveguide combined body.

  As shown in FIG. 1, a package component 1 containing an optical element includes a case body 11-1 and an exterior body 11-2 that is integrated with the case body 11-1 by being combined with the case body 11. A case 10 is provided. In FIG. 1, the exterior body 11-2 is an example in which the case body 11-1 is integrated with the case body 11-1, but may be a sheath (tube shape), for example, and may be a cover shape. And may be divided into two or more.

  The first optical fiber member 100 and the second optical fiber member 200 are provided at two end portions 11a and 11b which are provided along a predetermined position of the case main body 11-1, for example, along the longitudinal axis and which face each other. Are fixed by optical fiber holding parts 12 and 13 for holding the respective parts. The first and second optical fiber members 100 and 200 have an input side and an optical signal according to the input direction of the optical signal to the optical waveguide coupler 20 and the output direction of the optical signal from the optical waveguide coupler 20, respectively. Functions as an output side.

  The optical waveguide combination 20 is an optical element, for example, as will be described later with reference to FIGS. 3 and 4, but a first fiber array 40 in which a first optical fiber member 100 is fixed to an optical waveguide device 30 formed in an array. And the second fiber array 50 to which the second optical fiber member 200 is fixed are joined and integrated. In this example, the first optical fiber member 100 has a structure in which a core material, that is, an optical fiber 101 is covered with a covering material 111. Further, the second optical fiber member 200 is a flat (tape-like) fiber member in which a plurality of core members, that is, optical fibers 201 (eight in this example) are arranged in a generally planar shape via a covering material 211. Thus, each optical fiber 201 has a structure arranged substantially parallel to each other.

  As shown in FIG. 2, the first optical fiber member 100 is a tube (optical fiber introduction member) passed through a hole (optical fiber introduction portion) 12 a formed in advance at a predetermined position of the corresponding optical fiber holding portion 12. ) 14 and introduced into the case body 11-1. The second optical fiber 200 member is formed in the case main body 11-1 through a tube (optical fiber introducing member) 15 that is passed through a hole (optical fiber introducing portion) 13a formed in a predetermined position of the optical fiber holding portion 13 in advance. Introduced inside. The first and second fiber introduction members, that is, the tubes 14, 15 are formed by the shape characteristics of the first and second fiber members 100, 200, the thickness of the covering materials 111, 211, or the core material, that is, the optical fiber 101, The number may be omitted according to the number of 201 or the like.

  The cores of the first and second optical fiber members 100 and 200 guided through the tubes 14 and 15 into the case main body 11-1, that is, the optical fibers 101 and 201, correspond to the corresponding optical fiber arrays 40 and 50. It is fixed at a predetermined position. Needless to say, when the tube 14 or 15 is omitted, the first or second fiber member 100 or 200 is directly introduced into the fiber introduction portion 12a or 13a.

  In this state, an adhesive (hereinafter referred to as an adhesive) having a first characteristic is applied to the covering member 111 of the optical fiber member 100 guided into the case main body 11-1 through the boundary portion between the tube 14 and the optical fiber holding portion 12 and the tube 14. The case main body 11-1 and the optical fiber member 100 are fixed by supplying 16 (referred to as a first adhesive). The first adhesive 16 may be attached to the optical fiber (core material) 101 in a state of protruding from the covering material 111 of the optical fiber member 100 toward the optical waveguide assembly 20. Further, when the optical fiber member 100 is fixed to the optical fiber holding portion 12 by the first adhesive 16, the optical fiber 101 is bent in the case body 11-1, and microbending, that is, a slight bending structure is formed. In order not to occur, it is preferable that a predetermined tension is applied.

  Similarly, the first adhesive 16 is supplied to the covering portion 211 of the optical fiber member 200 guided through the tube 15 and the boundary portion between the tube 15 and the optical fiber holding portion 13 and into the case main body 11-1. Thus, the case main body 11-1 and the optical fiber member 200 are fixed. Further, the first adhesive 16 may adhere to the eight optical fibers (core members) 201 in a state of protruding from the covering material 211 of the optical fiber member 200 toward the optical waveguide assembly 20. Further, when the optical fiber member 200 is fixed to the optical fiber holding portion 13 by the first adhesive 16, the optical fiber 201 bends within the case body 11-1, and microbending, that is, a slight bending structure is formed. In order not to occur, it is preferable that a predetermined tension is applied.

  In accordance with such an assembling process, the optical waveguide assembly 20 is temporarily suspended or at least partially in contact with the bottom 11-c of the case body 11-1 in the middle of the assembly. In a state where the positional relationship of the straight line is within 11-1, it is positioned at a predetermined position within the case body 11-1. The first adhesive 16 is at least a lid-like body 11 in a state where an exterior body integrated with the case body 11-1, for example, a lid member 11-2, is attached or fixed to the case body 11-1. -2 is supplied to the case 10 without contacting at least one surface of the case 10 at a predetermined position in the case body 11-1 so as not to contact -2. The exterior body 11-2 is not limited to a lid shape as long as it can be integrated with the case body 11-1, and may be, for example, a sheath (tube shape), or a lid shape with two or more. As described above, it may be divided into two.

  With such a configuration and assembly process, the optical fiber 101 that is the core of the first optical fiber member 100, the eight optical fibers 201 that are the core of the second optical fiber member 200, and the optical fibers 101, The optical waveguide member 20 that is optically connected and fixed to 201 is substantially straight along a virtual line 10-1 that can be regarded as a substantially straight line in the case 10 in the cross-sectional direction shown in FIG. Fixed in shape. In this embodiment, the optical fiber 201 has a tape shape in which a plurality of optical fibers are arranged in parallel. Therefore, the optical fiber 201 is parallel to a plane in which a plurality of optical fibers 201 are arranged. Only in the direction, it is fixed in a substantially straight line in the case 10 along the virtual line 10-1 that can be regarded as a substantially straight line. Further, the optical fiber 101, the optical fiber 201, and the optical waveguide member 20 are fixed in the case 10 without microbending by this configuration and the assembly process.

  As described above, even if the first adhesive 16 expands or contracts that may cause stress fluctuations such as mechanical force and thermal expansion from the outside, the effect of the first adhesive 16 is reduced. 20 is reduced. The optical fiber members 100 and 200 are fixed to the corresponding optical fiber holding portions 12 and 13 in a state where a predetermined tension is applied until the first adhesive 16 is cured. Even when a mechanical force is applied from the outside or when a stress change occurs due to thermal expansion or the like, the optical fibers 101 and 201 are not bent and microbending does not occur, and the optical characteristics are not easily changed. The first adhesive 16 has a high elasticity, has a physical property that the elongation at the time of cutting is 100% or more, particularly 200%, a low viscosity when uncured, and a low hardness after curing. It is a hardener addition (attachment) type and can be easily obtained from Shin-Etsu Chemical Co., Ltd. under the trade name KE1206, for example.

  Also, the optical waveguide assembly 20 does not cause a chemical reaction such as inhibition of curing with the first adhesive 16 and has a second characteristic different from that of the first adhesive 16 (hereinafter referred to as the first adhesive 16). 2) (referred to as adhesive No. 2) 17 and fixed at a predetermined position in the case main body 11-1. Therefore, even when mechanical force is applied to the case 10 from the outside or when expansion or contraction that may cause stress changes such as thermal expansion due to fluctuations in ambient temperature occurs, for example, the optical waveguide assembly 20 It is prevented that the optical fibers 101 and 201 of the first and second optical fiber members 100 and 200 that are joined to each other are bent to cause microbending. Accordingly, the degree of fluctuation in optical characteristics caused by the stress change, for example, fluctuation in power (intensity) of transmitted light (optical signal) is reduced.

  Specifically, the second adhesive 17 covers at least the entire surface of the optical waveguide combined body 20 (that is, wraps around the optical waveguide combined body 20), and at least by the case main body 11-1 and the exterior body 11-2. It is supplied to a predetermined position in the case body 11-1 so that a predetermined gap can be held in the internal space of the case 10 to be defined.

  More specifically, the second adhesive 17 is not in direct contact with the first adhesive 16, or is exposed from the first adhesive 16 even when it is in contact with the first adhesive 16 (protruded). ) In a state of slightly contacting each of the optical fibers 101 and 201, it is supplied and cured in the case main body 11-1. In this case, the 2nd adhesive agent 17 can osmose | permeate the clearance gap which may arise between the optical waveguide coupling body 20 and the bottom part 11-c of the case main body 11-1. In addition, although it is possible that the 2nd adhesive agent 17 contains a bubble, a problem does not arise in particular.

  In other words, even if the second adhesive 17 is in a state where an exterior body, for example, a lid-like body (or a sheath-like body) 11-2 is attached or fixed to the case main body 11-1, at least a lid-like body ( Or a sheath-like body) 11-2 and the optical waveguide member are not in direct contact with each other, and at least have a predetermined gap in the internal space of the case 10 defined by the case body 11-1 and the exterior body 11-2. Thus, it is supplied to a predetermined position in the case main body 11-1. That is, the total amount of the second adhesive 17 is the exterior body (lid body or sheath body) with the exterior body (lid body or sheath body) 11-2 fixed to the case body 11-1. The amount is not limited to contact with at least one surface of the case 10 including 11-2.

  Therefore, even when a mechanical force is applied from the outside through the case main body 11-1, the transmission of the force to the optical waveguide combined body 20 by the second adhesive 17 is reduced. The second adhesive 17 is a hardener-added (attached) type gel-like silicone system in which a predetermined viscoelasticity remains in a cured state. For example, the trade name KE1051 (from Shin-Etsu Chemical Co., Ltd.) A and B) are easily available.

  As described above, the optical waveguide assembly 20 is the core material of the first and second optical fiber members 100 and 200 fixed to the optical fiber holding portions 12 and 13 via the first adhesive 16. By being connected to the optical fibers 101 and 201, the position is not in contact with the case main body 11-1, or only a small part is in contact with the case main body 11-1 at a predetermined position in the case main body 11-1. Has been. The optical fiber members 100 and 200 are given a predetermined tension (tensile force) so that the optical fibers 101 and 201 are not bent and microbending is not generated until the first adhesive 16 is cured. Since the optical fiber holders 12 and 13 are fixed in a corresponding state, the optical characteristics fluctuate even when a mechanical force is applied from the outside or when a stress change occurs due to thermal expansion or the like. Hateful.

  Further, the optical waveguide assembly 20 is stretched by the second adhesive 17 to the case main body 11-1, that is, the package component 1, which may cause stress fluctuations such as mechanical force and thermal expansion from the outside. Even if it is a case, it is being fixed in the case main body 11-1 in the state which the influence is hard to be transmitted.

  Moreover, even if the 1st and 2nd adhesives 16 and 17 change the environment where the package components 1 are placed, for example, temperature is in the range of -40 to 85 ° C., each does not contact each other or only a small region. Is supplied and hardened in the case main body 11-1.

  That is, for example, even when the first and second optical fiber members 100 and 200 are deformed due to thermal expansion or the like and a stress change occurs, the stress change is caused by the extension of the first adhesive 16. Is transmitted to the optical fibers 101 and 201 that are the cores of the optical waveguide members 20 and 100 and 200 connected to the optical waveguide connector 20. Even if the second adhesive 17 itself is deformed due to thermal expansion or the like, the stress change caused by the deformation is connected to the optical waveguide coupler 20 or the individual optical fiber members connected to the optical waveguide coupler 20. Transmission to the cores 100, 200, that is, the optical fibers 101, 201 is reduced.

  Accordingly, the first and second adhesives cause variations in optical characteristics caused by stress changes in the optical fiber members 100 and 200, such as the degree of non-uniformity of loss and the transmitted optical signal (light). The magnitude of fluctuations in the power (intensity) of the slab will be reduced.

  3 and 4 are schematic diagrams for explaining an example of an optical element incorporated in the package component shown in FIGS. 1 and 2. 3 and 4, the optical element 20 can be connected to an optical fiber having a single core at one end (the core material of the first optical fiber member 100 described with reference to FIGS. 1 and 2, that is, the optical fiber 101), and The other end is an optical waveguide of an array shape formed so as to be connectable to each (8 channels) of a multi-core (8-core) optical fiber (the core material of the second optical fiber member 200 in FIG. An optical fiber member having 8 cores (multi-core) by branching an optical signal input through a single core optical fiber member by combining the device (30) and the fiber array (40, 50), that is, an optical waveguide combined body. This is an example of an optical branching device that outputs to the output. The optical element can be used as an optical coupler that combines optical signals input from the respective core members and outputs them to a single-core optical fiber member, for example, when the input side is an 8-core side. Needless to say.

  As shown in FIG. 4, the optical waveguide coupler 20 removes the optical waveguide device 30 functioning as an optical branching device or an optical coupler, and the coating material 111 of the first optical fiber member 100 on the optical waveguide device 30. The cores exposed by removing the covering material 211 of the second optical fiber member 200 from the first optical fiber array 40 and the optical waveguide device 30 for fixing the optical fiber 101 as the exposed core material. The second optical fiber array 50 that fixes the eight optical fibers 201, which are materials, is joined by joint surfaces L1 and L2.

  For example, when an optical signal is input from the optical fiber 101 of the first optical fiber member 100 connected by the first optical fiber array 40, the optical waveguide device 30 functions as an optical branching device, and the second light When optical signals are input from the optical fibers 201 (eight) of the second optical fiber members 200 connected by the fiber array 50, they function as an optical coupler. More specifically, the optical waveguide device 30 functions as an optical branching device when an optical signal is input through the optical fiber 101 of the first optical fiber member 100, and the optical signal input to the single core 30 a ( Light) is distributed at a predetermined ratio to each of the multi-core cores 30b made of an arbitrary number (eight) of core members. The optical waveguide device 30 also functions as an optical coupler when an optical signal is input through the eight optical fibers 201 of the second optical fiber member 200, and an optical signal (light) input to each of the cores 30b. Is introduced into the single core 30a.

  An optical waveguide device 30 shown in FIG. 4 has, for example, a core 30a, cores 30b (eight), and individual cores on a substrate 30S such as silicon (Si) or a quartz glass wafer having a predetermined thickness. An optical material layer 31 (hereinafter referred to as a clad) functioning as a clad layer by being given a predetermined relative refractive index difference is laminated. When the substrate 30S is made of, for example, a silicon wafer, the optical material layer used for the individual cores 30a and 30b is compared with the optical material used for the cores 30a and 30b before being formed on the substrate 30S. Needless to say, an under-cladding layer (not shown) having a low refractive index is formed to a predetermined thickness. Further, the refractive indexes of the cores 30a and 30b of the optical waveguide device 30 are defined to be 0.1 to several percent higher than the refractive indexes of the substrate 30S and the clad 31, respectively. In this example, the relative refractive index difference, which is the difference between the refractive indexes of 30a and 30b and the refractive indexes of the substrate 30S and the clad 31, is about 0.45%.

  As shown in FIG. 3A, the first fiber array 40 includes a substrate 40S and a lid (cover glass) 41. The core material of the single-core optical fiber member 100 described above with reference to FIGS. 1 and 2, that is, the optical fiber 101 is set in the V-groove 40a provided in the substrate 40S, and the adhesive 42 is supplied. The substrate 40S and the cover glass (lid) 41 are fixed. Therefore, the optical fiber 101 is positioned by the V-groove 40a and fixed at a predetermined position of the first fiber array 40 with an accuracy defined according to the positional accuracy of the V-groove 40a with respect to the substrate 40S.

  The optical fiber member 100 is introduced to the optical waveguide device 30 side through the inside of the tube 14 inserted into the hole 12a formed in the optical fiber holding portion 12 as shown in FIG. 1 and FIG. As explained.

  The second fiber array 50 has a substrate 50S and a lid (cover glass) 51 as shown in FIG. The core material of the multi-core optical fiber member 200 described above with reference to FIGS. 1 and 2, that is, the eight optical fibers 201 is set in the V-groove 50a provided on the substrate 50S, and the adhesive 52 is supplied. As a result, the substrate 50S and the cover glass (lid) 51 are fixed. Accordingly, each optical fiber 201 is positioned by the V-groove 50a and fixed at a predetermined position of the second fiber array 50 with an accuracy defined according to the positional accuracy of the V-groove 50a with respect to the substrate 50S.

  The optical fiber member 200 is connected to the optical fiber holding unit 13 through the tube 15 inserted in the hole 13a formed in a shape corresponding to the outer shape of the covering material 200a of the optical fiber member 200. The introduction to the 30 side is as described above with reference to FIGS. 1 and 2.

  The first and second fiber arrays 40 and 50 are respectively positioned in the positions previously described with reference to L1 and L2 in FIGS. 1 and 2, for example, with a light curable adhesive having translucency, respectively. It is joined with. Thereby, each of the optical fibers 101 and 201 (eight) is optically connected to the core 30a and the core 30b (8 channels) of the optical waveguide device 30.

  5 (a) and 5 (b) are placed in an environment of about −40 to 85 ° C. which is a temperature condition when the package component of the present invention shown in FIGS. The figure shows the amount of fluctuation in the power of the optical signal (light) when a variation in shape, which is a factor causing a stress change in the first and second adhesives 16 and 17, is given. 5A and 5B show an optical signal input to the optical fiber member 100 described above with reference to FIGS. 1 and 2, that is, the single-core optical fiber 101, by the optical waveguide device 30. The relationship between the temperature cycle of the temperature test of the optical signal (light) branched from eight channels and output from each of the individual optical fibers 201 (eight) of the optical fiber member 200 and the amount of power fluctuation is described. . 6 (a) and 6 (b) show the second adhesive 17 in FIGS. 1 and 2 for comparison with the results shown in FIGS. 5 (a) and 5 (b). It is the schematic explaining the relationship between the temperature cycle of the temperature test of each output light, and the variation | change_quantity of power when it fills in the case main body 11-1 so that the lid | cover 11-2 of case 10 demonstrated may be contact | connected. is there. FIGS. 5A and 6A show light having a wavelength of 1310 nm, which is a representative wavelength on the short wavelength side, which is used for evaluating the loss of an optical waveguide or an optical fiber, respectively. FIG. 6B and FIG. 6B show light having a wavelength of 1550 nm, which is a typical wavelength on the same wavelength side.

  5 (a) and 5 (b), in the package component of the present invention shown in FIGS. 1 to 4, the light power fluctuates in the temperature test cycle, that is, in the temperature change of −40 to 85 ° C. It is recognized that the amount is suppressed to about 0.1 [dB] at maximum for light of any wavelength. On the other hand, in the comparative example shown in FIGS. 6A and 6B, the fluctuation amount of the light power is the package component of the present invention shown in FIGS. 5A and 5B. It can be seen that the light of any wavelength reaches about three times as much as the amount of fluctuation in.

  That is, according to the package component of the present invention shown in FIGS. 1 to 4, an undesirable change in stress is reduced in the optical fiber incorporated therein in the temperature range of −40 to 85 ° C.
