CLASSICAL OPTICAL CORPUSCULAR THEORY OF S EMICONDUCTOR-LASER INTENSITY SQUEEZED-LIGHT GENERATOR

Fluctuations of the stored energy and emitted power of a semiconductor laser are derived by a simple model in which the light is considered as a classical particle flow. The fundamental noise source is the shot noise associated with field to absorbing or emitting atoms conversion . The mirror loss noise is taken into account in the form of a classic al partition noise. For quiet pumping conditions the pump is no more a noisy process and a non-fluctuating optical output is possible. The t heory allows the description of the intensity squeezed (i.e. non-class ical) states of light and its results agree with quantum theory. Optim al conditions for squeezed state of light generation and characterizat ion are pointed out.
