CdS_xSe_(1-x)玻璃条型波导光双稳全开关动力学特性的研究

Study on the Optical Bistability in CdS_xSe_(1-x)-Doped Glass Waveguide

本文采用光纤端面耦合技术,在入射功率为6mW的情况下,观测到掺CdSxSe1-x半导体微晶玻璃条型波导中上升和下降时间分别为20和30ps的光学双稳跳跃过程,并从实验数据估算出CdSxSe1-x玻璃的三阶非线性系数x（3）为1×10-9esu。

The paper reports the optical bistability in CdSxSe1-x-doped glass waveguide with rise and fall times of 20 ps and 30 ps in distable switching by means of fribe coupling input with a power of about 6 mW. The third nonlinear susceptibility(x3)of CdSxSe1-x-doped glass is estimated experimentally to be 1×10-9esu. The high sweed stitching and value of x（3）show that the optical bistability is caused by an optical nonlinearity attributed to the band-filling effect.
