Abstract
The coupling of longitudinal-optical bulk phonons to grating induced intersubband resonances was investigated for electrons in a GaAs quantum well by far-infrared transmission and reflection spectroscopy. The density dependence of the mode frequencies is in good agreement with predictions for a well embedded in two semi-infinite half spaces of the barrier material. A strong asymmetry of the line shape was observed that arises from influence of the grating coupler.
