Abstract
At the UCSB free-electron laser we have realized a set-up to detect the photoluminescence from semiconductor quantum structures while they are irradiated with intense far-infrared radiation. The effect of the radiation on both quantum wells and quantum-well wires has been identified with non-resonant carrier heating. The confined carriers in these structures have energy-level spacings in the far-infrared region of the spectrum. The tunability of the free-electron laser therefore allows the study of resonant effects as well.
