Abstract :
AlGaInAs lasers with integrated beam-expanders (IBEs) have been fabricated for the first time. The thickness of the multiple-quantum-well (MQW) active layers was vertically tapered by using selective area growth (SAG). A maximum operating temperature has reached 145°C. The beam divergence in the vertical direction was drastically reduced from 41.7° (without IBEs) to 18.0° (with IBEs)
