Paper Abstract

Large positive and negative Goos-Hänchen(GH) shifts on an symmetrical metal-cladding waveguide (SMCW) were investigated both theoretically and experimentally. The SMCW is simply a glass slab with several hundred micrometers sandwiched between two gold films. A recently developed free-space coupling technique was used to transfer the light energy into the ultrahigh order modes of the SMCW. It is shown that during the resonant excitation, and the intrinsic damping coincides with the radiative damping of the modes, the lateral shifts of reflected beam are enhanced to as large as hundreds of micrometers. It is also known that sign of the GH shift is totally dependent on the difference between the radiative damping and the intrinsic damping. GH shifts with sub-millimeter scale were experimentally observed. The experimental results show good agreement with theoretical prediction.
