利用LiNbO3波导电光棱镜,验证了导波光束偏转器的双稳态特性.对此,利用调制特性曲线的高斯函数模型,作了必要的理论分析,与测量结果基本相符.

The testability of the optical guided-wave beam deflector has been demonstrated for the first time. For this, the Gaussian function model of the modulation characteristio curve is presented by where I is the sampling output light intensity, and Im is the maximum of I. D is the normalized coefficient of the sampling detection, and Ds is the contribution from the background light in D. V is the modulating voltage, and Vm is corresponding to I = Im and D = l. Vd is used to represent the width of the d V curve. Theoretical analysis using this model agrees with the measured results basically.
