Abstract

We find that photons from a light emitting diode injected with Poissonian electrons have superPoissonian statistics when the differential efficiency is larger than the mean emission efficiency of the device. This result shows the limitation of a conventional theory which describes the generation of sub-Poissonian light in terms of Poisson point process.
