Quantum Statistic Properties of the Squeezed Chaotic Light

研究压缩混沌光场的量子统计性质。压缩混沌光场在动量P分量上具有明显的压缩效应,并呈现光子聚束和超泊松分布等特性。光场的压缩效应越强,平均光子数、光子数涨落就越大。在相空间中光场的Wigner函数为高斯态分布,且不存在负部区域。

Quantum statistical properties of squeezed chaotic light was investigated. The results showed that squeezing effect in momentum P is clear and it brings bunching effect and Super-Poisson distribution. For the chaotic state,the stronger the squeezing is,the larger the photon number average and fluctuation is. Wigner function is also analytically derived. It can be found that Wigner function is Gaussian in phase space, and there is no negative region.
