Abstract
Photoelectron-counting distributions are obtained for modulated radiation sources, with arbitrary modulation waveforms and depths. Cases treated in detail include chaotic, amplitude-stabilized, and Risken sources, with square-wave, triangular, and sinusoidal modulation. Modulation is shown to broaden the counting distributions, an effect interpretable as accentuated photon bunching. The broadening is not marked for the chaotic source, but the shape of the distribution changes drastically for the amplitude-stabilized source. Varying the radiation statistics and the modulation waveforms can produce a variety of counting distributions, from double peaked to extremely flat. Modulation may serve to accentuate the distinctions between counting distributions associated with sources of different radiation statistics.
