利用级联型波导结构来增强古斯－汉欣位移．用两块完全相同的对称金属包覆波导制备级联型波导，研究了反射光束的古斯－汉欣位移增强效应．结果表明，当激光在级联型波导之间反射8次、波长从859．630 nm变化到859．673 nm时，古斯－汉欣位移大于5 mm，消光比可以达到50 dB．

Enhancement effect of Goos-H?nchen ( GH) shift by using the cascaded optical waveguide structure which was constructed by two oppositely placed symmetric metal-cladding waveguide was studied in this paper.It is ex-perimently demonstrated that as the light reflects 8 times between the cascaded optical waveguiedes and the wavelength changes from 859.630 nm to 859.673 nm, the GH shift exceeds 5 mm and the corresponding extinction ratio reaches 50 dB.
