Definitions
- the present invention relates to, for example, an optical module equipped with a heater and a ring resonator.
- optical waveguide ring resonators In optical communications, optical waveguide ring resonators (sometimes simply called ring resonators) are used as optical filters to process light. Optical waveguide ring resonators are small and can achieve periodic transmission wavelength characteristics, so they are widely used as tunable filters, optical switches, and modulators. The transmission wavelength of an optical waveguide ring resonator is determined by the ring length and the refractive index of the waveguide, and wavelength tunability can be achieved by temperature control using a microheater loaded on the optical waveguide.

Therefore, with the technology described in Patent Document 1, part of the heat from the heater is also transferred to the SOI substrate, making it impossible to efficiently transfer the heat from the heater to the ring resonator structure.

- Fig. 2 is a cross-sectional view of the optical module 1. Specifically, Fig. 2 is a cross-sectional view of the optical module 1 taken along line AA' shown in Fig. 1.
- the optical module 1 includes a ring resonator 10, a heater 20, a first substrate 30, and a gap 50.
- the optical module 1 includes a ring resonator 10, a heater 20, a first substrate 30, a second substrate 40, and a gap 50.
- the ring resonator 10 has at least a ring-shaped optical waveguide 11.
- Light is incident on the ring-shaped optical waveguide 11 included in the ring resonator 10, and only light of a certain wavelength of the incident light is output from the ring-shaped optical waveguide 11.
- the wavelength of the output light is determined by the length of the ring-shaped optical waveguide 11 and the refractive index of the optical waveguide.
- the ring resonator 10 may further include a waveguide that guides light to be incident on the ring-shaped optical waveguide 11 and a waveguide that guides the light output from the ring-shaped optical waveguide 11 to another optical element.
- the heater 20 is provided inside the ring-shaped optical waveguide 11 included in the ring resonator 10. Specifically, the heater 20 is provided inside the first substrate 30 in a first region that has the ring-shaped optical waveguide 11 as its outer periphery when light passes through the first substrate 30 in a direction perpendicular to the surface of the first substrate 30. As shown in FIG. 2, the heater 20 is disposed at the same height as the ring resonator 10 in a direction perpendicular to the surface of the first substrate 30 (thickness direction of the first substrate 30 (up and down direction on the paper surface of FIG. 2)). The heights of the heater 20 and the ring resonator 10 may be different from each other.
- Figure 3 is a diagram in which the first region R1 is added to Figure 1 with diagonal lines.
- Figure 4 is a diagram in which the three-dimensional regions of the first substrate 30 and the second substrate 40 corresponding to the first region R1 are added to Figure 2 with diagonal lines.
- the three-dimensional region corresponding to the first region R1 refers to the region where the figure of the first region R1 extended in a direction perpendicular to the surface of the first substrate 30 overlaps with the first substrate 30 and the second substrate 40.
- the first region R1 has an outer periphery that is the shape of the ring-shaped optical waveguide 11 when light passes through the first substrate 30 from a direction perpendicular to the surface of the first substrate 30.
- the inner periphery of the ring-shaped optical waveguide 11 is the outer periphery of the first region R1, but the outer periphery of the ring-shaped optical waveguide may be the outer periphery of the first region R1.
- the three-dimensional region corresponding to the first region R1 has a columnar shape with the shape of the ring-shaped optical waveguide 11 as it passes through the first substrate 30 from a direction perpendicular to the surface of the first substrate 30 as its bottom surface.
- the three-dimensional region corresponding to the first region R1 is a region sandwiched between a part of one bottom surface of the first substrate 30 (the upper surface in FIG. 4) and a part of the other bottom surface of the first substrate 30 (the lower surface in FIG. 4). That is, in the examples shown in FIG. 1, FIG. 2, FIG. 3, and FIG. 4, the three-dimensional region corresponding to the first region R1 has a columnar shape with the shape of the ring-shaped optical waveguide 11 as its bottom surface on each of the two bottom surfaces of the first substrate 30.
- the heater 20 is disposed so that the distance from the bottom surface of the first substrate 30 (e.g., the top surface in Figures 2 and 4) is the same as the distance from the bottom surface of the first substrate 30 (e.g., the top surface in Figures 2 and 4) to the ring-shaped optical waveguide 11.
- the ring-shaped optical waveguide 11 and the heater 20 may be disposed so that these distances are different.
- the heater 20 generates heat in response to the power input from a drive circuit (not shown). As a result, the heater 20 heats the ring-shaped optical waveguide 11. Specifically, the heater 20 heats the first substrate 30 and the ring-shaped optical waveguide 11. Note that in the examples of Figures 1 and 3, the shape of the surface of the heater 20 when passing through the first substrate 30 from a direction perpendicular to the surface of the first substrate 30 is rectangular, but it may also be a polygon with more than a rectangle, an arc, a circle, or an ellipse.
- the second substrate 40 is a plate-like substrate that contains at least silicon, for example.
- the second substrate 40 is stacked in a first direction on the first substrate 30.
- the second substrate 40 also has a hole 41.
- the hole 41 is formed in the surface that contacts the first substrate 30 among the surfaces that constitute the second substrate 40.
- the second substrate 40 is bonded to the first substrate 30 via an area of the surface of the second substrate 40 that faces the first substrate 30 other than the area in which the hole 41 is provided.
- the void 50 is the space inside a hole provided on the surface of the second substrate 40 facing the first substrate 30.
- the void 50 is formed to include at least the region of the first region R1 that is located between the first substrate 30 and the second substrate 40 (second region R2, described below).
- the void 50 is filled with, for example, argon. The details of the void 50 will be described using Figures 5 and 6.
- FIG. 5 shows a portion of the three-dimensional region corresponding to the first region R1 shown in FIG. 4 as the second region R2.
- the second region R2 is a portion of the three-dimensional region corresponding to the first region R1 that is located between the first substrate 30 and the second substrate 40.
- FIG. 6 is a top view of the second substrate 40. As shown in FIG. 6, the second substrate 40 has a hole 41. Furthermore, the void 50 is a space located inside the hole 41. In this case, the hole 41 is formed such that the void 50 includes at least the second region R2.
- the second region R2 has a bottom surface whose outer periphery is the shape of the ring-shaped optical waveguide 11, similar to the three-dimensional region corresponding to the first region R1. Therefore, the second region R2 has a columnar shape whose bottom surface has the same shape as the ring-shaped optical waveguide 11, similar to the three-dimensional region corresponding to the first region R1.
- the distance between the two bottom surfaces in the second region R2 can be set arbitrarily.
- the optical module 1 includes a ring resonator 10, a heater 20, a first substrate 30, a second substrate 40, and a gap 50.
- the ring resonator 10 has a ring-shaped optical waveguide 11 and is attached to the first substrate 30.
- the heater 20 is provided inside the first substrate 30 within a first region R1 that has the optical waveguide 11 as its outer periphery when light passes through the first substrate 30 from a direction perpendicular to the surface of the first substrate 30, and heats the ring resonator 10.
- the second substrate 40 is laminated on the first substrate 30.
- the gap 50 is located between the first substrate 30 and the second substrate 40, and is formed so that the first substrate 30 and the second substrate 40 are spaced apart within the first region R1.
- the heat from the heater 20 is transferred to the second substrate 40 before reaching the ring-shaped optical waveguide 11. Therefore, the heat from the heater 20 cannot be efficiently transferred to the ring-shaped optical waveguide 11 (ring resonator structure).
- the optical module 1 has a gap formed in the first region R1 so that the first substrate 30 and the second substrate 40 are separated when passing through the first substrate 30 from a direction perpendicular to the surface of the first substrate 30.
- the first region R1 has the shape of the optical waveguide 11 as its outer periphery, so the gap 50 is formed in the region of the first substrate 30 where the first region R1 is located. Therefore, the heat from the heater 20 is not transmitted to the second substrate 40 until it is transmitted to the ring-shaped optical waveguide 11. As a result, the heat from the heater 20 can be efficiently transmitted to the ring-shaped optical waveguide (ring resonator structure). This allows the optical module 1 to suppress power consumption in the heater 20.
- the heater 20 is disposed at a position including the center of the first region R1 around the optical waveguide 11.
- a typical heater for heating an optical waveguide may be disposed near the optical waveguide in order to efficiently heat the optical waveguide.
- the gap 50 is formed, so the heater 20 can already efficiently heat the optical waveguide, and therefore the heater 20 may be disposed at a position including the center of the first region R1 around the optical waveguide 11. This eliminates the need to provide the heater 20 near the optical waveguide, improving the degree of freedom in the shape and position of the heater 20. This allows more freedom in determining the locations of other optical and electronic components in the optical module 1.
- the optical module 1A is a first modified example of the optical module 1.
- FIG. 7 is a diagram for explaining the optical module 1A.
- the optical module 1A includes a ring resonator 10, a heater 20, a first substrate 30, a second substrate 40, and a gap 50, similar to the optical module 1.
- the second substrate 40 does not have a hole 41
- the first substrate 30 has a hole 31.
- the gap 50 is a space formed inside the hole 31 of the first substrate 30.
- the first substrate 30 is bonded to the second substrate 40 through an area of the surface of the first substrate 30 facing the second substrate 40 other than the area where the hole 31 is provided.
- the optical module 1B is a second modified example of the optical module 1.
- FIG. 8 is a diagram for explaining the optical module 1B.
- the optical module 1B includes a ring resonator 10, a heater 20, a first substrate 30, a second substrate 40, and a gap 50, similar to the optical module 1.
- the optical module 1B further includes a third substrate 60.
- the third substrate 60 is stacked in a first direction with respect to the first substrate 30 and the second substrate 40.
- the first direction refers to the up-down direction indicated by the arrow A1 in FIG. 8.
- the second substrate 40 does not have a hole 41
- the third substrate 60 has a hole 61. Therefore, the gap 50 is a space formed inside the hole 61 of the third substrate 60.
- the optical module 1C is a third modified example of the optical module 1.
- FIG. 9 is a diagram for explaining the optical module 1C.
- the optical module 1C includes a ring resonator 10, a heater 20, a first substrate 30, a second substrate 40, and a gap 50, similar to the optical module 1.
- the first region R1 and the second region R2 are shown similar to FIG. 5.
- the gap 50 is shown to be larger than the second region R2.
- the gap 50 may be the same size as the second region R2, as shown in FIG. 9.
- Fig. 10 is a block diagram showing a configuration example of the optical module 2.
- Fig. 11 is a cross-sectional view of the optical module 2. Specifically, Fig. 11 is a cross-sectional view of the optical module 2 taken along line BB' shown in Fig. 10.
- Fig. 12 is a view in which a three-dimensional region corresponding to the first region R1 has been added to Fig. 11.
- the optical module 2 includes a ring resonator 10, a heater 20, a first substrate 30, and a gap 50.
- the optical module 1 includes a ring resonator 10, a heater 20, a first substrate 30, a second substrate 40, and a gap 50.
- the ring resonator 10 has a ring-shaped optical waveguide 11 and is attached to the first substrate 30.
- the heater 20 is provided in the first substrate 30 within a first region R1 that surrounds the optical waveguide 11 when light passes through the first substrate 30 from a direction perpendicular to the surface of the first substrate 30, and heats the ring resonator 10.
- the second substrate 40 is laminated on the first substrate 30.
- the gap 50 is located between the first substrate 30 and the second substrate 40, and is formed so that the first substrate 30 and the second substrate 40 are separated from each other within a three-dimensional region corresponding to the first region R1.
- the heat from the heater 20 is transferred to the second substrate 40 before reaching the ring-shaped optical waveguide 11. Therefore, the heat from the heater 20 cannot be efficiently transferred to the ring-shaped optical waveguide 11 (ring resonator structure).
