摘要

An apparatus includes an extended cavity vertical cavity surface emitting laser producing light and having an active region, a first reflector position adjacent to a first side of the active region, an extended cavity positioned adjacent to a second side of the active region, and a second reflector reflecting a first portion of the light into the extended cavity and transmitting a second portion of the light, a planar waveguide positioned adjacent to the extended cavity vertical cavity surface emitting laser, and a horizontal coupler structured to couple the second portion of light from the extended cavity vertical cavity surface emitting laser into the waveguide.
