摘要
利用二维环形周期极化铌酸锂，提出一种角度不敏感的Solc型电光滤波器。发现二维环形周期极化铌酸锂能够克服角度依赖问题，它能为不同方向入射的光提供不变的倒格矢以维持准相位匹配。计算表明，利用二维环形周期极化铌酸锂制作而成的Solc型电光滤波器，其中心透过波长在偏离正入射情况下仍然保持不变。这种新型的角度不敏感Solc型滤波器可在多角度、多光束同时滤波。
An angular-independent Solc-type electro-optical filter based on two-dimensional （2D） angularly periodically poled LiNbO3 is presented. We find that the 2D angularly poled LiNbO3 can provide invariable radial reciprocal vectors which can be used in designing angular-independent Solc-type electro-optical filter. The study demonstrates that the Solc-type filter based on 2D angularly poled LiNbO3 can keep its central passing wavelength unchanged even though the incident light deviate from the normal incidence. The angular-independent Solc-type electro-optical filter can find its application in multi-angle, multi-beam filtering.
