Abstract :
Summary form only given. Pump noise suppression in a constant-current driven semiconductor laser or LED is known to be the key mechanism in generating sub-Poissonian light from these sources. We have developed a theoretical model that describes their pumping mechanism. Pumping is considered to be the injection of carriers into the active layer across the depletion region. An independent Poisson equation that describes the junction voltage dynamics is introduced.
