Electromodulation of excitons in quantum wells measured by photoluminescence

In this paper, we shall describe a modulated photoluminescence technique which, in semiconductors quantum wells, provides results similar to the conventional electromodulated absorption measurements. The advantage of this new technique is that it can be used on as grown samples or devices without the need for elaborate sample geometries or sample preparation which are necessary in the modulated absorption measurements.© (1995) COPYRIGHT SPIE--The International Society for Optical Engineering.
