Quantum versus classical descriptions of sub-Poissonian light generation in three-wave mixing

Popis výsledku v původním jazyce

Sub-Poissonian light generation in non-degenerate three-wave mixing is studied numerically and analytically withing quantum and classical approaches. Husimi Q-functions and their classical trajectory simulations are analysed to reveal a special regime corresponding to the time-stable sub-Poissonian photocount statistics of the sum-frequency mode. Conditions for the observation of this regime are discussed. Theoretical predictions of the Fano factor and explanation of the extraordinary stabilization of the sub-Poissonian photocount behaviour are obtained analytically0 by applying the classical trajectories. Scaling laws for the maximum sub-Poissonian behaviour are found. Noise suppression levels in non-degenerate versus degenerate three-wave mixing arediscussed on different time scales compared to the revival times. It si shown that the non-degenerate conversion offers much better stabilization of the suppressed noise in comparison to the degenerate process.
