Fiber assembly for facet optical coupling

1. An apparatus, comprising:

a photonic chip including a planar surface and a pillar on the planar surface;

a fiber v-groove block having a first v-groove, wherein the first v-groove is aligned with the pillar such that the pillar is at least partially within the first v-groove; and

a rod disposed within the first v-groove between the pillar and the fiber v-groove block,

wherein the fiber v-groove block further comprises a second v-groove, and wherein the apparatus further comprises an optical fiber disposed at least partially within the second v-groove.

2. The apparatus of claim 1 , wherein the rod is a first rod, and wherein the fiber v-groove block further comprises a third v-groove, wherein the second v-groove is between the first and third v-grooves, and wherein the apparatus further comprises a second rod disposed at least partially within the third v-groove.

3. The apparatus of claim 1 , wherein the optical fiber is in contact with the planar surface of the photonic chip.

4. The apparatus of claim 1 , further comprising a compressible foam between the optical fiber and the photonic chip.

5. An apparatus, comprising:

a photonic chip including a planar surface and a pillar on the planar surface;

a fiber v-groove block having a first v-groove, wherein the first v-groove is aligned with the pillar such that the pillar is at least partially within the first v-groove; and

a rod disposed within the first v-groove between the pillar and the fiber v-groove block,

wherein the fiber v-groove block has a first end proximate the photonic chip and a second end distal the photonic chip, and wherein the optical fiber is recessed from the first end.

6. The apparatus of claim 5 , further comprising a lid, wherein the optical fiber is between the fiber v-groove block and the lid, and wherein the lid is recessed from the first end of the fiber v-groove block.

7. The apparatus of claim 5 , further comprising a lid, wherein the optical fiber is between the fiber v-groove block and the lid, and wherein the lid has a thinned portion proximate the first end of the fiber v-groove block and a thick portion thicker than the thinned portion proximate the second end of the fiber v-groove block.

8. An apparatus, comprising:

a photonic chip including a planar surface and a pillar on the planar surface;

a fiber v-groove block having a first v-groove, wherein the first v-groove is aligned with the pillar such that the pillar is at least partially within the first v-groove and such that the pillar is in contact with a first side and a second side of the v-groove; and

a rod disposed within the first v-groove between the pillar and the fiber v-groove block.

9. The apparatus of claim 8 , wherein the fiber v-groove block further comprises a second v-groove, and wherein the apparatus further comprises an optical fiber disposed at least partially within the second v-groove.

10. The apparatus of claim 9 , wherein the rod is a first rod, and wherein the fiber v-groove block further comprises a third v-groove, wherein the second v-groove is between the first and third v-grooves, and wherein the apparatus further comprises a second rod disposed at least partially within the third v-groove.

11. The apparatus of claim 9 , wherein the optical fiber is in contact with the planar surface of the photonic chip.

12. The apparatus of claim 9 , further comprising a compressible foam between the optical fiber and the photonic chip.

13. The apparatus of claim 9 , further comprising a lid, wherein the optical fiber is between the fiber v-groove block and the lid, and wherein the lid is recessed from an end of the fiber v-groove block.

14. The apparatus of claim 9 , further comprising a lid, wherein the optical fiber is between the fiber v-groove block and the lid, and wherein the lid has a thinned portion proximate a first end of the fiber v-groove block and a second portion thicker than the thinned portion proximate a second end of the fiber v-groove block.
