STRUCTURE FOR ATTACHING AN OPTICAL FIBER TO A PLANAR WAVEGUIDE AND METHOD THEREOF

摘要

A planar optical waveguide (100) is provided. The waveguide (100) includes a substrate (110) having a top surface, a first end, an opposing second end, and a first channel (120) extending from the first end toward the second end along the top surface. The first channel (120) has a first sidewall extending toward the second end (118), and an endwall engaging the first sidewall and the second sidewall. A cladding layer (144) is disposed on the top surface of the substrate. A core (142) is disposed within the cladding layer. The core has a first end generally co-planar with the endwall and a second end. A method of manufacturing the waveguide and connecting the waveguide to an optical fiber is also provided.
