Abstract:

The usual semiclassical theory of light detection has been demonstrated to be valid only in the absence of feedback from detector to source. A revised theory has been developed that is valid even in the presence of such feedback. Research has begun on the possibility of using various heterostructures including quantum-well devices that might serve as solid-state versions of the space-charge-limited Franck-Hertz experiment this experiment produced the first source of cw photon-number-squeezed light, reported in 1985. Keywords Photon, Number squeezed light, Theory, Light detection, Excess, Noise factor.
