Patent ID: 8422525

Claim:
A semiconductor laser comprising: a gallium nitride substrate having a semipolar crystalline surface region characterized by and an orientation of greater than about 2 degrees from an (11-22) plane toward a (0001) plane, but less than about 50 degrees, and having an m-direction, and a c-projection direction perpendicular to the m-direction; a laser region formed over the semipolar crystalline surface region, the laser region having a cavity orientation substantially parallel to the m-direction and extending from a first end to a second end, and having an indium concentration sufficient to cause emission of polarized light of about at least 490 nm wavelength; a first cleaved m-face facet on the first end; and a second cleaved m-face facet on the second end; wherein the laser region emits light polarized substantially parallel to the c-projection direction.
