Claim 4:
5. The ultraviolet laser diode device of claim 1, further comprising:
a ridge structure configured with the n-type aluminum, gallium, and nitrogen containing material to form an n-type ridge structure;
a dielectric material overlying the n-type aluminum, gallium, and nitrogen containing material; 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 an n-type gallium and nitrogen containing material overlying the n-type aluminum, gallium, and nitrogen containing material, such that the active region is configured between the first transparent conductive oxide material and the second transparent conductive oxide material to provide an optical guiding effect within the active region, and the ridge structure is configured with at least a pair of side wall regions having an upper surface region between the pair of side wall regions.
