提供了一种研究半导体在光学非性状态下的动态光谱方法.将此方法应用到半导体CdS上,观察到在热光非线性状态下,其透过光谱(在吸收带边缘附近)随时间的变化(在ms数量级上).计算机模拟结果与实验相符,并得出了在CdS上获得室温光学双稳态的条件.

This article introduces a new method for dynamic spectral study of a semiconductor under its optical nonlinearity condition. With this method, a semiconductor GdS in the optical nonlinearity is investigated, it can be observed that the CdS's transmitting spectra (at the edge of the absorbing band) are varying with time (at the ms degree). The computer imitating calculation consists with the experimental result. The conditions have been found for realizing the room temperature optical bistabi-lity on CdS.
