电光调制器的温度特性及其最优化设计  

陈海波   佘卫龙  

利用线性电光效应的波耦合理论对铌酸锂晶体电光调制器的温度特性进行研究,给出了不同光波波矢和晶体光轴夹角情况下电光效应的温度变化特性,发现可以利用角度调节来克服电光调制器的温度敏感性;在此基础上,进一步对电光调制器进行了最优化设计,得到一个半波电压小(几十伏)、零场泄漏几乎为零(零电压出射光强和入射光强比为0.0027)、消光比达到365.6、温度性能稳定而且不需要透明电极的一个设计。

A wave coupling theory of linear electrooptic effect has been used to study the temperature dependence of electrooptic modulator. The numerical results of temperature dependence have been obtained from this method under different angels between incident light vector and crystal optical axis. The results show that temperature stability of electrooptic modulator can be obtained by angle modulation. An optimal design of electrooptic modulator has also been presented, which has the advantages of a very small zero-field leakage, a relatively small half-wave voltage, a large extinction ratio and good stability of output intensity versus temperature. And the design doesn't need transparent electrodes.
