Acousto-optic switch for telecommunication networks

Abstract

A detailed description of multichannel Bragg cells and their insertion in a versatile crossbar optical switch architecture is presented here. The cells utilize for the first time an acousto-optic scattering geometry in GaAs which displays advantageous characteristics in the design of a telecommunication spatial switch: low crosstalk and access delay, insensitivity to optical polarization, relatively low insertion losses.
