提出了在单模光纤中利用非简并四波混频产生压缩态的方法。沿着理论的一个实验上可行的检测策略的近简并混合过程的分析，在现实的光纤向前传播。通过将光纤介质视为非谐振子的集合来模拟光学非线性和吸收的量子性质的影响。抑制不希望的影响，如受激布里渊散射的方法，是一种技术，用于提供相移的本地振荡器波检测压缩所必需的。光纤表征和四波参量荧光检测的初步实验进行了说明。
Nondegenerate four-wave mixing in a single-mode optical fiber is proposed as a method of squeezed state generation. An analysis of the near-degenerate mixing process for forward propagation in realistic fibers is presented along with the theory of an experimentally feasible detection strategy. The effects of the quantum nature of the optical nonlinearity and absorption are modeled by treating the fiber medium as a collection of anharmonic oscillators. Methods of suppressing undesired effects such as stimulated Brillouin scattering are presented as is a technique for providing the phase-shifted local oscillator wave necessary for the detection of squeezing. Preliminary experiments on fiber characterization and the detection of four-wave parametric fluorescence are described.
