Investigation on Generation and Detection of Squeezed State THz Light

概述了利用光学整流、参量振荡、空气等离子体等非线性过程产生THz光的方法.根据量子光学的压缩态概念,提出利用非线性光学过程实现压缩态THz光的可能性;并论述了压缩态THz光可具有消除系统所有的经典噪声,达到最大信噪比,实现超高灵敏度、超高精度的弱光信号传输和测量的优良效果.

The methods to generate the THz Light by optical rectification, parametric generators and air plasmas are described in outline. According to quantum optics on the concept of squeezed states, using of nonlinear optical processes to achieve the possibility of THz squeezed states are proposed ; and the THz squeezed states which have discussed in the paper have some excellent effects of all the classic noise cancellation in system, maximum SNR, high sensitivity, ultra high-precision measurement of weak light signal transmission and measurement.
