Abstract:
A high thermal conductivity (HTC) layer for use in an optoelectronic device, comprising:an adhesion layer to bind any III-V oxides with materials of said optoelectronic device that are adjacent to said adhesion layer; a dielectric waveguide layer that provides optical confinement for a guided optical mode, wherein said dielectric waveguide layer is fixedly connected to said adhesion layer; a highly heat conductive layer relative to the material within the optical gain region of an optoelectronic device within which said HTC layer is used, wherein said highly heat conductive layer is fixedly connected to said dielectric waveguide layer; and a stress compensation layer to compensate for the film stress built up in said adhesion layer and said highly heat conductive layer, wherein said stress compensation layer is fixedly connected to said highly heat conductive layer, wherein said stress compensation layer reduces any tendency of said adhesion layer and said highly heat conductive layer to delaminate due to differences in thermal expansion coefficients.
