PHOTONIC INTEGRATED CIRCUIT EDGE COUPLER STRUCTURE WITH REDUCED REFLECTION FOR INTEGRATED LASER DIODES

摘要

A photonic chip, an edge coupler for an integrated photonic system and a method for coupling a laser to the photonic chip. The edge coupler includes a waveguide of the photonic system having a longitudinal axis. The longitudinal axis of a waveguide of the photonic chip is aligned with a longitudinal axis of the laser. The facet of the waveguide facing the laser is at a non-perpendicular angle with respect to the longitudinal axis. Light is transmitted from the laser into the waveguide via the angled facet.
