Claim Text:
1. A hybrid laser apparatus comprising: a first semiconductor region including an active region of one or more layers of semiconductor materials from group III, group IV, or group V semiconductor, wherein the layers of the first semiconductor region include an ohmic contact layer coupled with a first electrical contact layer, a cladding layer coupled with the ohmic contact layer, a separated confinement hetero-structure (SCH) layer coupled with the cladding layer, a carrier blocking layer coupled with the SCH layer, a multiple quantum well (MQW) layer coupled with the SCH layer, and an indium phosphide layer coupled with the MQW layer, wherein a surface of the indium phosphide layer is coupled with a surface of a layer of a second semiconductor region; and the second semiconductor region coupled with the first semiconductor region, wherein the second semiconductor region includes at least a buried insulating layer and a silicon layer disposed on the buried insulating layer, and further includes: wherein the first, second, third and fourth trenches are disposed inside the silicon layer to have a portion of the silicon layer between a respective trench and the buried insulating layer, and wherein the first and second trenches define the optical waveguide.
