ABSTRACT:
Optical coupler apparatus having reduced geometry sensitivity includes spaced apart first and second main waveguides having a coupling section. In one embodiment, first and second side waveguide sections are arranged in the coupling section adjacent outer sides of the first and second main waveguides to allow evanescent coupling between the main waveguides and side waveguide sections. Methods of fabrication and operation are also described.
