Abstract:
1. A device comprising: a gallium and nitrogen containing surface having a {30-31} crystalline orientation, the {30-31} crystalline orientation being selected from either (30-31) or (30-3-1); an active region overlying a portion of the gallium and nitrogen containing surface; a laser stripe region formed overlying the active region, the laser stripe region being characterized by a cavity orientation parallel to a projection of the c-direction, the laser stripe region having a first end and a second end; a first facet provided on the first end of the laser stripe region, the first facet being substantially orthogonal to the laser stripe region; and a second facet provided on the second end of the laser stripe region, the second facet being substantially orthogonal to the laser stripe region, wherein the {30-31} crystalline orientation is off-cut less than +/−3 degrees toward or away from a c-plane, and the active region is configured to emit light characterized by a wavelength ranging from about 500 nm to about 580 nm, or from about 430 nm to about 480 nm.
