Abstract:
An intermediate ultraviolet laser diode device includes 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; 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.
