Abstract
A coupling system for photonic integrated circuits and integrated optical waveguides is provided. A recess is formed in a substrate on which one or more integrated optical waveguides are disposed, the recess being located at the desired mounting location of the photonic integrated circuit. At least one end wall of the recess is inclined with respect to a normal to the substrate surface. At least one end face of a photonic integrated circuit is inclined to match the inclined end wall of the recess. The length, width, and depth of the recess are controlled so that inserting the photonic integrated circuit into the recess passively provides both lateral and vertical alignment of the photonic integrated circuit with the integrated optical waveguide(s).
