Abstract

We report a strong selective enhancement of electronic intersubband excitations of a modulation-doped GaAs-Al0.2Ga0.8As quantum well placed inside an AlAs-Al0.4Ga0.6As planar lambda microcavity. By using specific angles for the incident and scattered light, both the exciting laser and the scattered photons can be tuned into resonance with the cavity mode. Since the width of the high-quality ...
