Patent ID: 8634442

Claim:
An optical device comprising: a gallium and nitrogen containing substrate member having an m-plane nonpolar crystalline surface region characterized by an off-cut orientation; a laser stripe region formed overlying a portion of the m-plane nonpolar crystalline orientation 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; a first cleaved c-face facet provided on the first end of the laser stripe region, the first cleaved c-face facet being characterized by a first scribed region; a second cleaved c-face facet provided on the second end of the laser stripe region, the second cleaved c-face facet being characterized by a second scribed region; and a wall plug efficiency of 14 percent and greater characterizing the optical device for at least 60 mWatt of optical output power.
