Electro-optic X-switch using single-mode Ti:LiNbO ₃ channel waveguides

Abstract

A new type of single-mode four-port electro-optic switch is investigated. The operation principle is based on the electrically controlled two-mode interference in the intersection region of two crossing single-mode channel waveguides. The switch is analysed numerically by the beam-propagation method, and is realised experimentally by using Ti:LiNbO3 channel waveguides.
