An electrically pumped GaAs-based vertical cavity surface emitting laser is demonstrated that uses an upper p-type GaAs/air-gap distributed Bragg reflector. The air gaps are realised by selective removal of AlGaAs sacrificial layers. Low threshold at room temperature is obtained using this fabrication scheme.
