Abstract
A new theoretical approach towards the tuning of Goos–Hänchen shift and Imbert–Fedorov shift for the reflected light beam is observed, designed and simulated in this paper through electro-optically tunable liquid crystal at an incident wavelength of 1550nm within the communication window. Here the considered Kretschmann–Raether geometry comprises a ZnSe prism and a liquid crystal layer of E44 between two metal layers of silver, where with the application of electric field from (0–10)V electro-optically tuning of the Goos–Hänchen shift from 64.09µm to −53.408µm and the Imbert–Fedorov shift from 122.8µm to −32.5µm for a change in refractive index of the liquid crystal layer from 1.52–1.79 are envisaged. This idea expedites the scope of fine tuning in optical switching within the µm ranges.
