| 摘 要： | 前期的工作已经证明，由于共振效应和渗透深度的增加，利用毫米尺度对称金属包覆波导和自由空间耦合技术，可获得毫米量级的古斯 -汉欣(Goos-H.nchen)位移。本文在此基础上，利用一对对称金属包覆波导组成级联型结构，研究了这种结构中古斯 -汉欣位移的增强效应。实验结果表明：当激光波长变化 43 pm时，由 CCD探测器测量得到的古斯 -汉欣位移达到了 2 215 μm，约为单级波导古斯 -汉欣位移的 2倍，实验结果与理论推导完全一致。 |

| Abstract: | According to the previous study, we have proved that, by using the symmetrical metal-cladding optical waveguide with millimeter scale and the free-space coupling technique, one millimeter order of Goos-H.nchen shift can be obtained due to the resonance effects and the increase of the penetration depth. On the basis of this, enhancement of Goos-H.nchen shift is demonstrated with a pair of symmetrical metal-cladding optical waveguides in a cascaded structure. It is experimentally shown that the Goos-H.nchen shift measured from a CCD detector is 2215 μm with a change of 43 pm in the light wavelength, which is just two times of that exhibited from a single waveguide. Experimental result agrees well with the theoretical prediction. This method shows potential application prospect in optical switching and filtering. |
