ABSTRACT:
A method of forming an optical component on a substrate structure includes forming a ridge in a light transmitting medium positioned on a base. The ridge includes a waveguide region configured to propagate light signals and a flange region extending across a longitudinal axis of the waveguide region. The method also includes removing at least a portion of the flange region so as to expose a facet aligned with the waveguide region such that light signals propagated along the waveguide region are transmitted through the facet.
