啁啾光脉冲在正色散介质中的量子传输

Quantum Propagation of Optical Pulse with Initial Chirp in the Normal dispersion Media

用一种新提出的通用的非线性光脉冲传输的量子理论，我们研究了具有啁啾的光脉冲在正色散克尔介质中传输时的压缩比变化情况。数值结果表明，正色散克尔介质中，光脉冲还是压缩态，但压缩和负色散克尔介质比起来弱一点，初始的负啁啾有利于压缩。

Based on a newly developed general quantum theory of nonlinear optical pulse propagation, the change of the squeezing ratios are studied as the propagation of the optical pulse with initial chirp in the normal dispersion Kerr media. Numerical results show that the squeezing still survives, but the squeezing is weaker in the normal dispersion media than in the anormal dispersion media and the initial negative chirp is benefit for squeezing.
