چکیده
|
Large tunable lateral shift from guided wave surface plasmon resonance (gwspr) is theoretically predicted. the dip of reflectivity and magnitude of the lateral shift can be controlled by the thickness of silver layer. the position of minimum reflection and maximum goos-hänchen (gh) shift can be conveniently adjusted by guided layer. the largest gh shifts at the optimal thickness of silver film can be hundreds of wavelengths when gwspr is excited. the numerical calculation results from the gaussian beam are in accordance with theoretical results.
