Photo-detection wait time distributions for light from degenerate parametric oscillator

Reeta Vyas, Luis F. Morales Bultron, Surendra Singh

Analytic expressions for conditional and unconditional wait-time distributions for the n-th photo-detection are derived for the light from a degenerate parametric oscillator and subthreshold laser, in the small photon number regime where quantum effects dominate.

Nonclassicality of light from a degenerate parametric oscillator

Arnab Mitra, Reeta Vyas, Surendra Singh

The nonclassical nature of light from a degenerate parametric oscillator is discussed in terms of criteria based on direct photon counting probabilities of light. These criteria do not rely on phase sensitive detection and reveal the nonclassical nature of the field where the conventional criteria based on moments of light intensity (like sub-Poissonian statistics or anti-bunching) fail. We also consider the effect of detector efficiency on the signature of nonclassicality and find that under certain circumstances inefficient detection can enhance nonclassical behavior.

Photon-counting statistics of the degenerate optical parametric oscillator

Reeta Vyas, Surendra Singh

Nonclassical light beams generated by the degenerate optical parametric oscillator operating below threshold are analyzed in terms of photoelectron-counting sequences. The positive-P representation is used to calculate the generating function for photoelectron statistics in a closed form. This generating function is used to derive expressions for the photoelectron-counting and waiting-time distributions. The dependence of these distributions on mean photon number inside the cavity and efficiency of detection is studied. The relationship between photoelectron-counting sequence and the photon emission sequence is used to present a simple physical picture of light beams produced by the degenerate parametric oscillator.
