Claim Text:
1. A method for fabricating a laser diode device comprising: providing a gallium and nitrogen containing substrate member comprising a surface region, a release material overlying the surface region, an n-type gallium and nitrogen containing material; an active region overlying the n-type gallium and nitrogen containing material, a p-type gallium and nitrogen containing material; and a first transparent conductive oxide material overlying the p-type gallium and nitrogen containing material, and an interface region overlying the first transparent conductive oxide material; bonding the interface region to a handle substrate; subjecting the release material to an energy source to initiate release of the gallium and nitrogen containing substrate member; and forming a ridge waveguide region in or overlying the n-type gallium and nitrogen containing material to form an n-type ridge structure; forming a conductive oxide region overlying the n-type gallium and nitrogen containing material; and forming a metal material overlying the first transparent conductive oxide material; wherein the first transparent conductive oxide material is comprised of indium tin oxide or zinc oxide, and wherein the handle substrate is selected from a semiconductor, a metal, or a dielectric or combinations thereof.
