INTERSUBBAND TRANSITIONS IN QUANTUM WELLS
by Professors E. Rosenacher and B. Vinter, Thomson_CSG, Central Research Laboratory, Orsay (France) and B. Levine, AT & T Bell Laboratories, Murray Hill/NJ (U.S.A.)

Recent progress in epitaxial growth techniques of semiconductors has made it possible to synthesize artificial potential shapes for electrons in matter. In quantum wells, the confinement of electrons has led to the formation of subbands whose energy separation corresponds to infrared radiation and created a new field of applications of these structures for detection and nonlinear optics in the infrared. This pioneering volume (NATO ASI SERIES B288) details the latest advances in the physics of intersubband transitions and reports on current industrial applications, such as qu well infrared detectors and modulators. Noted authorities in this rapidly expanding field discuss the fundamentals of intersubbands transitions, optical linearities, and detection devices in chapters that include:

_Coupling of radiation into quantum well infrared detectors by the use of reflection grantings and waveguide structures
_Application of multiple quantum well infrared detectors to present and future infrared sensor systems
_Spectroscopy of quantum_dot atoms
_Electron transfer infrafred modulator
_Inelastic light scattering of electronic excitations in quantum wells
_Intersubband relaxation in modulation doped quantum well structures.
