Planar waveguide with patterned cladding and method for producing same

摘要

Integrated optical waveguides and methods for the production thereof which have a patterned upper cladding with a defined opening to allow at least one side or at least one end of a light transmissive element to be air clad. The at least one side or at least one end is, for preference, a lens structure unitary with the waveguide or a bend. Also provided is a method of fabricating an optical waveguide with a patterned cladding.

1. An integrated optical waveguide comprising:
a substrate; a light transmissive element disposed on the substrate and comprising a waveguide with a bend along a length thereof; and an upper cladding having a pattern which provides at least one region in the bend in which the light transmissive element has an air clad side surface and a top portion of the light transmissive element is air clad, and where the upper cladding comprises a polymeric material; and wherein the pattern of the upper cladding is different from that of the light transmissive element in the region of the bend.
