COUPLING SYSTEM FOR OPTICAL FIBERS AND OPTICAL WAVEGUIDES

摘要

An optical coupler may include a fiber optic structure that has a portion of an outer surface that is beveled at a predetermined angle relative to a longitudinal axis of the fiber optic structure. The beveled outer surface portion may be optically coupled with a waveguide core of an optical integrated circuit. The fiber optic structure may also include a second outer surface portion that is butt coupled to an end of an optical fiber to optically couple the second outer surface portion with the optical fiber.

主权项

1. A method comprising:
affixing an optical fiber in a channel formed in a slab to form an integrated structure, the optical fiber comprising a core portion and a cladding portion; and removing a first portion of the integrated structure from a second portion of the integrated structure at a predetermined angle defined relative to a longitudinal axis of the fiber optic structure, wherein the second portion has an outer surface portion that is beveled at the predetermined angle after removing the first portion from the second portion, and wherein the beveled outer surface portion comprises both the core portion and the cladding portion.
