Control of photon transport in an optical structure of four microresonators using spectral engineering

Abstract

Abstract A theoretical model of a photonic switch based on a T-shaped optical structure with combined switching control is considered. The transmission coefficient of photons through the structure varies between current and vacuum modes by several physical mechanisms. The main one is the resonant interaction between microresonators with adjustable photon tunneling energy. An alternative way is also pump compensation by switching on an additional laser field. The influence of the model parameters on the switching efficiency is studied. It is shown that this scheme can be implemented on the basis of already existing technologies.
