Study of Well Barrier Hole Burning in Quantum Well Bistable Lasers

Ganesh Madhan M., Vaya P.R., Gunasekaran N., Anna University, IN

Quantum carrier capture and release effects on optical bistability in multiple quantum well (MQW) lasers are studied using the well barrier hole burning model. The ratio of carrier capture to release time (h) is varied [...]

Study of Voltage Tunable Asymmetric Quantum Well Structure for Infrared Detection

Vaya P.R., Ananda Natarajan S., Srinivasan K.R., Indian Institute of Technology, IN

The performance of GaAs/AlGaAs asymmetric quantum well infrared detectors exhibiting inter subband absorption has been studied. The asymmetric quantum well structure considered for the present study consists of two regions, a step quantum well with [...]
