棱镜耦合方法在不可见光和非透明波导中进行的实验研究

Experimental research of prism coupling method for invisible optical light on opaque optical waveguide

本论文从理论上讨论了如何就给定的光波导选择恰当的耦合棱镜;从实验方面研究了不可见光(He-Ne,1.15μm)在透可见光的波导上的耦合情况。实验结果表明棱镜材料的色散影响可以用柱面镜来消除。最后给出了不可见光在不透可见光的波导(YIG/GGG)上的耦合结果。

In this paper, we theoretically discuss the selection of prisms for a given waveguide, experimentally research the coupling of invisible light (He-Ne,1.15μm) with a transparent waveguide. The result shows that a cylindrical lens can eliminate the dispersive effection of prism material. Finally, we realize the coupling of He-Ne, 1.15μm laser with YIG/GGG waveguide.
