| 摘 要： | 研究吸收对准相位匹配线性电光效应的影响,得到适用于吸收介质的准相位匹配线性电光效应的耦合波方程及其解析解.计算结果表明,吸收不但削弱光的强度,且影响o光与e光之间的电光耦合.当o光与e光的吸收系数不同时,由于它们之间的电光耦合,总输出光强随外加电场变化而变化.研究结果可用于吸收介质的电光器件设计.

| Abstract: | The effect of absorption on the quasi-phase-matched (QPM) linear electro-optic effect was investigated.The wave coupling equations for the QPM linear electro-optic effect in absorbent materials were derived,and the general solution to the resultant equations was obtained.Numerical results demonstrate that the absorption not only reduces the intensity of the light but also influences the electro-optic coupling.When the o- and e-ray experience different absorption in a crystal,the total output intensity changes with the external field due to the electro-optic coupling.The study would be useful for the design of electro-optic device made of absorbent QPM material. |
