摘要:
Excitonic resonances and the quantum confined Stark effect are observed near 1.3-mu-m in InGaAs quantum wells grown on GaAs using a slowly graded InGaAs buffer. The pin structure performs as a modulator with a relative transmission modulation of 12% at 1.3-mu-m and as a low leakage photo-detector.
