Claim 13:
14. An ultraviolet laser diode device operable at a wavelength of less than 380 nm and greater than 200 nm, the ultraviolet laser diode device comprising:
a handle substrate member comprising a surface region,
an interface region overlying the surface region;
a first transparent conductive oxide region with a band gap energy of greater than 3.2 eV overlying the interface region;
a p-type aluminum, gallium, and nitrogen containing material;
an active region overlying the p-type aluminum, gallium, and nitrogen containing material;
an n-type aluminum, gallium, and nitrogen containing material;
a ridge structure; and
a second transparent conductive oxide material with a band gap energy of greater than 3.2 eV overlying an exposed portion of the n-type aluminum, gallium, and nitrogen containing material or overlying an exposed portion of a gallium, and nitrogen containing material overlying the n-type aluminum, gallium, and nitrogen containing material, such that active region is configured between the first transparent conductive oxide region and the second transparent conductive oxide material to provide an optical guiding effect within the active region
wherein a process of forming the ultraviolet laser diode device comprises:
bonding the interface region to the surface region; and
subjecting a release material to an energy source to initiate release of the n-type aluminum, gallium, and nitrogen containing material from the release material.
