CATALOG DESCRIPTION: Introduction to semiclassical and fully quantized theory of laser leading to noise, coherent, and modulation properties of laser light, with emphasis on semiconductor laser. The quantum concept of photon and photodetection will be formulated. T he theory will be applied to describing noise in optical amplifier and photodetection. The effect of optical feedback on laser will be covered. The inhibition and enhancement of spontaneous emission in microcavity and nanophotonic device structures will be discussed.
