Single and multilayer waveguides and fabrication process

摘要

An optoreflective structure for reflecting an optical signal following a path defined by an optical waveguide comprising a first cladding layer having a first planar cladding surface; a waveguide disposed on the first cladding layer; and a second cladding layer disposed on the waveguide and having a second planar cladding surface. The first cladding layer, the second cladding layer and the waveguide terminate in a generally dove-tailed structure having a beveled planar surface. An optoreflector is disposed on the beveled planar surface for a changing direction of an optical signal passing through the waveguide. Methods of producing the optoreflective structure are disclosed.
