Abstract

A grating (18) couples the waveguide region (36) of a semiconductor laser (11) to a dielectric waveguide (26). The waveguide region of the laser includes a mirror (15) at one end thereof and an absorber (19) at the other end thereof. The dielectric waveguide includes a reflector (24) therein to reflect a portion of the light coupled from the laser to the dielectric waveguide back into the laser waveguide region.
