We propose and investigate theoretically the Kerr squeezing of light at a wavelength of 2 µm in chalcogenide fibers with large nonlinearity and-this is the advance-with much reduced attenuation. We present suitably realistic but straightforward designs of low-loss step-index single-mode fibers with the nonlinear Kerr coefficient 3 to 4 orders of magnitude higher than for standard telecommunication fibers, and we give estimations of optimal squeezing for continuous wave laser signal in the considered fibers based on or glasses.
我们提出并从理论上研究了在具有大非线性且衰减大大降低(这是进展所在)的硫族化物光纤中2微米波长光的克尔压缩。我们给出了低损耗阶跃折射率单模光纤的合理现实但简单的设计,其非线性克尔系数比标准电信光纤高3至4个数量级,并且我们基于碲酸盐或锗酸盐玻璃对所考虑光纤中的连续波激光信号的最佳压缩进行了估计。
