摘要

我们简要地回顾了我们最近在半导体掺杂玻璃中光学非线性的实验结果。结果表明,即使在吸收边缘以下,非线性也是由非线性吸收决定的。发现光学克尔效应具有与非线性折射相当的磁化率。我们还发现,在简并四波混频中,观测到的强度依赖性会受到非线性吸收的强烈影响。

Optical nonlinearities in semiconductor-doped glasses near and below the band edge
We present a brief review of our recent experimental results on optical nonlinearities in semiconductor-doped glasses. It is shown that even below the absorption edge the nonlinearities are determined by nonlinear absorption. The optical Kerr effect is found to have a susceptibility which is comparable to that for nonlinear refraction. We also find that in degenerate four-wave mixing the observed intensity dependence can be strongly influenced by nonlinear absorption.
