Patent ID: 8254425

Claim:
An optical device comprising: a gallium nitride substrate member having a semipolar or nonpolar crystalline surface region; an n-type gallium nitride region overlying the surface region, the n-type gallium nitride region having a thickness ranging from about 500 nm to 2000 nm; an active region overlying the n-type gallium nitride region, the active region comprising 3 to 5 or 5 to 7 quantum wells; a laser stripe region formed overlying the active region, the laser stripe region being characterized by a cavity orientation substantially parallel to a first-direction, the laser stripe region having a first end and a second end, the laser stripe region comprising a p-type gallium nitride region, the p-type gallium nitride region having a thickness ranging from about 500 nm to about 1000 nm; an n-type metal region overlying a backside of the gallium nitride substrate member; an overlying p-type metal region overlying an upper portion of the laser stripe; a first cleaved m-face facet provided on the first end of the laser stripe region; and a second cleaved m-face facet provided on the second end of the laser stripe region.
