Abstract
The present invention is collimator making process. A collimator is set inside a V groove and its self-focusing lens is shifted repeatedly in x, y and z directions to change the direction and focus position of the outgoging light from the collimator. When the outgoing light is reflected by the total reflector to the collimator and the power meter measures the maximum value, the position of the self-focusing lens is fixed relatively to the capillary to obtain the special performance of that the outgoing light is parallel to the mechanical axle of the cylindrical sleeve. The present invention may find its wide application in place where the collimator is inserted like a connector.
Description
The present invention relates to a kind of field of fiber optic passive device, refer in particular to a kind of method for making of collimating apparatus.
In the most structure that adopts as shown in Figure 1 of the collimating apparatus of optical fiber at present commonly used.101 is optical fiber cable; 102 is the single fiber head, and 104 is GRIN Lens.103 is fixed fiber head and autohemagglutination lens cylindrical jacket.Optical fiber head end face and GRIN Lens end all adopt 82 ° of left and right sides angles of wedge, so that the return loss of collimating apparatus reaches more than the 50dB, because the optical fiber head angle of wedge exists, there is the gap between optical fiber head and the GRIN Lens again, the emergent light of collimating apparatus generally departs from the mechanical axis of collimating apparatus, and its fleet angle is generally in less than 0-2 ° of scope.
This structure is in conventional passive device, because the mode that two collimating apparatuss adopt the relative adjustment device to give welding again, its light direction departs from its mechanical axis to be approved.But in some particular device, wish emergent light and accept optical collimator and can adopt the mode that directly patches to fix as the joints of optical fibre.The collimating apparatus that this method is made then can't meet the demands.
The object of the present invention is to provide a kind of emergent light direction quite strict with the parallel collimating apparatus method for making of its mechanical axis.
Technical scheme of the present invention is such:
Collimating apparatus is put into the V-type groove, place a completely reflecting mirror at V-type groove one end, this completely reflecting mirror plane is perpendicular to the sideline, bottom of V-type groove.Make completely reflecting mirror and GRIN Lens apart from the collimating apparatus operating distance half, change collimating apparatus emergent light direction and focal position along x axle or y axle or z direction of principal axis translation GRIN Lens repeatedly.When the collimating apparatus emergent light reflexes to collimating apparatus through completely reflecting mirror, when power meter reaches maximal value simultaneously, fixedly GRIN Lens and kapillary relative position.
The present invention makes collimating apparatus because it has emergent light and parallels property with its column type overcoat mechanical axis, and it is widely-used to be expected to wish that at some collimating apparatus can resemble in the device that connector connects acquisition, in MEMS devices such as (micro-machinery switchs).
Now further specify in conjunction with the accompanying drawings:
Fig. 1 is the prior art key diagram.
Fig. 2 is a light path principle figure of the present invention (a).
Fig. 3 is a light path principle figure of the present invention (b).
Fig. 4 is an index path of the present invention (a).
Fig. 5 is an index path of the present invention (b).

Fig. 7 is the fixing synoptic diagram (b) of GRIN Lens of the present invention.
Fig. 8 is the fixing synoptic diagram (c) of GRIN Lens of the present invention.
Principle of the present invention can be by expressing as the index path of Fig. 2 thin lens.
If luminous point A is △ y apart from the collimating apparatus mechanical axis
1, collimator lens is reduced to thin lens, and its optical center of lens O point apart from axis is-△ y
2The A point is on the thin lens focal plane.(see figure 2); A point and O point line then are the directional light directions behind the collimating device collimation, and its direction and collimating apparatus mechanical axis angle theta are
, wherein f is the focal length of lens.Clearly on optical center of lens point O, move △ y
1+ △ y
2Promptly with luminous point on mechanical axis when contour, the AO line is represented light direction, and is at this moment then parallel with mechanical axis.Be not difficult to find out, all can proofread and correct axis runout, realize that finally the collimating device collimation direction is parallel with the collimating apparatus mechanical axis by the method as O point both direction on x, y face.
Actual collimating apparatus is made as shown in Figure 3.
Employing is slightly less than 0.25Pitch (as 0.248Pitch) GRIN Lens and makes collimating apparatus.Figure 30 1 is an optical fiber cable, and 302 is metallic cylinder, and 303 is the optical fiber kapillary, and 304 is optical fiber head, and 305 is plane mirror.Its method for making is as follows:
The collimating apparatus of making is put into the V-type groove, place a completely reflecting mirror, adjust mirror angle, make from the collimating apparatus emergent light to reflect back into collimating apparatus, and power meter reaches maximal value through completely reflecting mirror at V-type groove one end.Fix completely reflecting mirror, promptly at this moment completely reflecting mirror is vertical with the sideline, bottom of V-type groove, shifts out the collimating apparatus that the collimating apparatus made makes desire and is placed in the V-type groove.The metallic cylinder 302 of collimating apparatus capillary portion is placed in the V-type groove, and 306 is fiber coupler, its a termination light source 308, one termination power meter 307.Catoptron is L apart from the GRIN Lens distance; This length is half for the collimating apparatus operating distance.From focus lens, change the collimating apparatus light direction in x, the translation of y direction, the z of translation simultaneously direction is adjusted the collimating apparatus focal position; Regulate repeatedly, make the collimating apparatus emergent light reflect back into collimating apparatus, arrive power meter by fiber coupler simultaneously through completely reflecting mirror.When its power reached maximal value, fixedly then to produce collimating apparatus emergent light direction parallel with its collimating apparatus mechanical axis for GRIN Lens and kapillary relative position.
The fixed form of GRIN Lens has three kinds, as Fig. 6, and Fig. 7, shown in Figure 8.
Among Fig. 6,41A is the collimating apparatus metallic cylinder, 42A is an optical fiber head, 44A is GRIN Lens, spherical lens or non-spherical lens, 43A is a UV glue, this collimating apparatus is fixed, and directly solidifies with UV glue or with epoxy glue at kapillary and place, slit, GRIN Lens side, but does not have glue on the logical light face of optical fiber head GRIN Lens.
Among Fig. 7, fixing UV glue or the epoxy glue of also adopting of collimating apparatus solidifies, and different with Fig. 6 is that UV glue or epoxy glue directly are full of optical fiber head and GRIN Lens end face.Because adopt the 0.25Pitch GRIN Lens, its glue-line is only at 10～30 mu m ranges, its stability and logical optical property still are guaranteed.Among Fig. 8,41C is a special facture cylinder metal urceolus, 42c is an optical fiber head, 43C is UV glue or epoxy glue, 45C is a GRIN Lens, the metal foil cover (or directly at GRIN Lens side plated with gold layer) of 44C for closely cooperating and bond with GRIN Lens has an empty gap scalable between 44C and the 41C.GRIN Lens and metallic cylinder 44C directly are welded on the collimating apparatus overcoat 41C.
Made collimating apparatus of the present invention is expected to wish at some that collimating apparatus can resemble in the device that connector is coupled and obtains widespread use, in MEMS devices such as (micro-machinery switchs) because it has emergent light and parallels property with its column type overcoat mechanical axis.
