一种光折变-等离子滤波器及其制作方法
摘要：
一种光折变-等离子滤波器，包括输入LiNbO3晶体、金属层以及输出LiNbO3晶体，输入LiNbO3晶体和输出LiNbO3晶体为X切Z传或Y切Z传的LiNbO3晶体，输入LiNbO3晶体和输出LiNbO3晶体之间为金属层，输入LiNbO3晶体和输出LiNbO3晶体上制作光折变光栅。以及一种光折变-等离子滤波器的制作方法，包括：金属复合LiNbO3晶体的制作；利用SPR波的相位匹配条件，确定对应各个滤波波长时的光栅周期，利用双光束干涉法分别在输入LiNbO3晶体和输出LiNbO3晶体中写入光折变光栅。本发明结构简单、制作方便、材料重复利用率较高、同时实现对透射光和反射光的利用。
摘要（英）：

The invention discloses a photorefraction-plasma filter which comprises an input LiNbO3 crystal, a metal layer and an output LiNbO3 crystal. The input LiNbO3 crystal and the output LiNbO3 crystal are X-cutting and Z-transmission or Y-cutting and Z-transmission LiNbO3 crystals, the metal layer is arranged between the input LiNbO3 crystal and the output LiNbO3 crystal, and photorefraction optical gratings are manufactured on the input LiNbO3 crystal and the output LiNbO3 crystal. The invention further discloses a manufacturing method of the photorefraction-plasma filter. The manufacturing method comprises the steps of manufacturing the metal composite LiNbO3 crystals, determining the optical grating period corresponding to each filter wavelength through the phase position matching conditions of SPR waves, and writing photorefraction optical gratings into the input LiNbO3 crystal and the output LiNbO3 crystal through the two-beam interference method. The photorefraction-plasma filter is simple in structure, convenient to manufacture and high in material repeating utilization rate, and utilizes transmission light and reflected light at the same time.
