OPTOELECTRONIC DEVICES

Radiometry and photometry. EM waves in heterostructures (Fresnell’s equations, films and AR coatings, quantum efficiency). Quantum theory (secondary quantization of EM field, Planck’s law, absorption, emission and stimulated emission of EM waves, absorption coefficient). Generation, recombination, drift and diffusion of charged particles in photodetector materials. Photodetectors (photo-conductive and photo-voltaic detectors, avalanche photodiodes, infrared detectors, noise). Light emitting devices (LED, injection semiconductor laser, laser oscillation conditions, trigger current).
