Distributed Bragg reflector (DBR) lasers emitting at 1062 nm using a first-order grating fabricated by holographic lithography in a GaAs waveguide layer have been realised for the first time. At room temperature the DBR lasers show excellent characteristics with a monomode output power of 180 mW at 300 mA.
