We report here 0.9 μm lasing in a p-n junction 2D photonic band gap (PBG) defect mode microcavity surface-emitting laser with electrical injection. The GaAs based device heterostructure is grown by metal-organic vapor phase epitaxy (MOVPE). It consists of an n+ GaAs contact layer, an n-type lower GaAs/Al0.8Ga0.2As distributed Bragg reflector (DBR) mirror, an undoped λ cavity (λ=0.94 μm) region with two 70 Å pseudomorphic In0.l5Ga0.85As wells in the middle and p-type AlGaAs and contact layers on the top. n- and p-type Al0.96Ga 0.04As layers are also inserted on the respective sides of the cavity region for eventual lateral wet-oxidation during the processing of the device. The photoluminescence emission peak from the quantum wells is observed at 940 nm
