提出了一种利用电光双折射网络实现的光波波形综合器。该综合器由偏振器、多块具有电光效应的双折射晶体和补偿器组成,输入余弦信号,组成一多级电光双折射网络。利用琼斯理论对该综合器进行了理论分析,根据扩展傅里叶级数系数正向对比法,实现了其他类型的周期性时域波形。给出一类三元综合器的分析与设计方法,得到合成矩形波与三角波所需的多组结构参量,并对输入信号误差及方位角误差对波形的影响进行了分析。
An optical waveform synthesizer based on electro-optic birefringence network is proposed. The synthesizer consists of a polarizer, a plurality of birefringent crystals with electro-optic effect and a compensator, and the cosine signal is input to form a multi-stage electro-optic birefringence network. The synthesizer is analyzed theoretically by Jones theory. According to the forward contrast method of extended Fourier series coefficient, other types of periodic time-domain waveforms are realized. The analysis and design method of a kind of ternary synthesizer is given. The multi-group structure parameters needed for synthesizing the rectangular wave and the triangular wave are obtained. The influence of the error of the input signal and azimuth error on the waveform is also analyzed.
