Claim 10:
11. An optical device comprising:
a gallium and nitrogen containing surface region;
an n-type gallium and nitrogen containing region overlying the surface region;
an active region overlying the n-type gallium and nitrogen containing region;
at least one quantum well region configured within the active region; and
a laser stripe region overlying a portion of the gallium and nitrogen containing surface region, the laser stripe region being characterized by a cavity orientation substantially parallel to the c-direction, the laser stripe region having a first end and a second end, the laser stripe region having a length of less than about 3000 microns and a width of less than about 50 microns,
wherein the first end comprises a first mirror surface having an anti-reflective coating and is configured to emit light characterized by a wavelength ranging from about 390 nm to about 420 nm or from about 420 nm to about 440 nm, and the second end of the laser stripe region comprises a second mirror surface having a reflective coating selected from silicon dioxide, hafnia, titania, tantalum pentoxide, zirconia, or aluminum oxide.
