Generation of nonclassical lights, such as photon-number squeezed states and quadrature-phase squeezed state, is required to realize optical communications and accurate measurements at sub-shot-noise levels. Among a variety of schemes, the direct generation of sub-Poissonian photon fluxes from semiconductor light emitters has been attracting much attention because of the simplicity of experimental arrangement, the low energy consumption, the possibility of a large degree of noise suppression, and the compatibility with modern communication system. In this presentation, we demonstrate the experimental results of generation of sub-Poissonian photon fluxes in an integrated light-emitter/detector system. It is shown that the pump-noise-suppression owing to the macroscopic Coulomb blockade effect can work well even when a superlattice alloylike material is used.
