摘要: 采用平面光波导电光调制器及简单的双光束干涉装置成功地进行了光学双稳态和多稳态的实验研究。光波导调制器是在自制的钛扩散铌酸埋平面光波导上蒸镀铝电极制成的。采取激光由调制器端面直接输入,由锗酸铋棱镜耦合输出的方式。实验中消除了锗酸铋晶体旋光性的影响。本文除了对光学双稳性进行了分析讨论外,还着重对不同形态的多稳实验回线进行了探讨。

Abstract: Using a planar optical waveguide electro-optic modulator and simple double beam interfering device, the experimental study of optical bistability and multistability is succesfully performed. The waveguide modulator is made by depositing Aluminium as electrodes on the Ti-diffused LiNbO3 planar optical waveguide which is fabricated by ourselves. Laser beam is coupled directly into the end of optical waveguide modulator and out of the Bi12GeO20 prism. Optical rotation arising from Bi12GeO21 crystal is overcome in experiment. In addition to analyzing and discussing optical bistability the multistabilitical hysteresis curves of different shapes obtained in experiments are particularly investigated. -
