Classification: CPC H | IPC H

Claim 7:
8. The ultraviolet laser diode device of claim 1, further comprising:
a second transparent conductive oxide layer with a band gap energy of greater than 3.2 eV overlying the n-type aluminum, gallium, and nitrogen containing material or overlying an exposed portion of an n-type gallium and nitrogen containing material overlying the n-type aluminum, gallium, and nitrogen containing material, such that an active region is configured between the first transparent conductive oxide material and the second transparent conductive oxide layer to provide an optical guiding influence;
a ridge structure configured within at least the second transparent conductive oxide layer to form transparent conductive oxide ridge structure;
a contact region to expose a portion of the second transparent conductive oxide layer; and
a metal contact material on the exposed portion of the second transparent conductive oxide layer.
