Strictly Nonblocking 8x8 Integrated Acoustooptic Space-Division Switch Array on LiNbO3,

Abstract

A number of architectures for integrated optic space-division Switching, using guided-wave electro-optic (EO) switches have been implemented in recent years. Unlike the guided-wave EO devices, guided-wave acoustooptic (AO) devices can facilitate a multiplicity of AO Bragg diffractions in the same interaction region of a planar waveguide by controlling the directivity of multiple input light beams, and the directivity and the carrier frequency of the surface acoustic waves (SAWs). Under such circumstances, proper design enables AO Bragg diffraction to take place between a designated pair of a light beam and a SAW without causing significant crosstalk to other similarly interacting pairs. In consummating the above idea, asymmetric and symmetric 4x4 nonblocking guided-wave AO space switches have been constructed recently.
