A method for manufacturing an optical device includes providing a carrier waver, provide a first substrate having a first surface region, and forming a first gallium and nitrogen containing epitaxial material overlying the first surface region. The first epitaxial material includes a first release material overlying the first substrate. The method also includes patterning the first epitaxial material to form a plurality of first dice arranged in an array; forming a first interface region overlying the first epitaxial material; bonding the first interface region of at least a fraction of the plurality of first dice to the carrier wafer to form bonded structures; releasing the bonded structures to transfer a first plurality of dice to the carrier wafer, the first plurality of dice transferred to the carrier wafer forming mesa regions on the carrier wafer; and forming an optical waveguide in each of the mesa regions, the optical waveguide configured as a cavity to form a laser diode of the electromagnetic radiation.

A die attach film structure includes a dicing film, an insulating adhesion layer including an upper surface and a lower surface opposite the upper surface, the lower surface of the insulating adhesion layer contacting an upper surface of the dicing film and including an insulating filler, and a conductive adhesion layer contacting an upper surface of the insulating adhesion layer and including a conductive filler.
