Abstract
A v-groove assembly is used to edge couple a lensed fiber (e.g., an optical fiber made of silica) with a waveguide in a photonic chip. The v-groove assembly is made from fused silica. Fused silica is used to so that an adhesive (e.g., epoxy resin) used in bonding the lensed fiber to the v-groove assembly and/or bonding the v-groove assembly to the photonic chip can be cured, at least partially, by light.

(canceled)
A method for optically coupling an optical fiber to a semiconductor waveguide, the method comprising:
- providing an optical assembly for connecting the optical fiber to the semiconductor waveguide, the optical assembly comprising:
- a v-groove assembly comprising:
- a base;
- a lid;
- a v-groove;
- and
- a facet, wherein the facet is for bonding the v-groove assembly to an optical chip;
- the optical fiber is positioned in the v-groove between the base and the lid;
- and
- epoxy bonding the optical fiber to the base and the lid, wherein the epoxy is, at least partially, cured using light;
- providing the optical chip, wherein the optical chip comprises the semiconductor waveguide;
- aligning the v-groove assembly with the optical chip so that the optical fiber aligns with the semiconductor waveguide;
- applying adhesive between the facet of the v-groove assembly and the optical chip so that the adhesive contacts both the facet of the v-groove assembly and the optical chip after the v-groove assembly is aligned with the optical chip;
- and
- irradiating the adhesive to, at least partially, cure the adhesive.
A system for coupling light from a chip to an optical network, the system comprising:
- a v-groove assembly comprising:
- a base;
- a lid;
- a v-groove;
- and
- a facet;
- an optical fiber bonded in the v-groove assembly between the base and the lid, wherein the optical fiber is bonded in the v-groove by an epoxy cured by ultraviolet light;
- and
- the chip having a waveguide, wherein the chip is bonded to the facet of the v-groove assembly by an adhesive so that an end of the optical fiber aligns with the waveguide of the chip.
A method for optically coupling an optical fiber to a semiconductor waveguide, the method comprising:
