近年来,在现代光学领域中出现了一个具有重要科学价值和广阔应用前景的新课题——光学双稳性。由于运用光学双稳器件的不同工作方式可以实现类似电子学器件的各种功能,从而引起了人们的极大兴趣。如利用双稳器件可以做成光学存储器、高速光开关、光控或电控实时光调制器;还可进行微分放大和光学限幅,实现光学延时和光逻辑运算等功能。因此有可能在光通讯、光学信息处理及未来
In recent years, in the field of modern optics has emerged a new subject with important scientific value and broad application prospects - optical bistability. Due to the different working methods of using optical bistable devices can achieve a variety of functions similar to electronic devices, which has aroused great interest. Such as the use of bistable devices can be made of optical memory, high-speed optical switches, light control or electronic control real-time light modulator; also differential amplification and optical limiting, optical delay and optical logic operations and other functions. It is therefore possible in optical communications, optical information processing and the future
