Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY LTD.
Field: Optics (Instruments)
Classification: CPC G | IPC G

Claim 10:
11. An optical system, comprising:
a substrate;
a waveguide disposed on the substrate;
an optical fiber optically coupled to the waveguide; and
an optical coupling device disposed between the optical fiber and the waveguide and configured to optically couple the optical fiber to the waveguide,
wherein the optical coupling device comprises:
a dielectric layer disposed on the substrate,
a multi-tip dielectric structure comprising an array of dielectric structures disposed within the dielectric layer, wherein the dielectric structures comprise dielectric tip ends and dielectric base ends, and
a semiconductor tapered structure, adjacent to the multi-tip dielectric structure, comprising a semiconductor tip end and a semiconductor base end wider than the semiconductor tip end, wherein the semiconductor base end is substantially aligned with the dielectric base ends.
