摘要：
Electro-optical switches composed of two Mach-Zehnder interferometer waveguides filled with 4-dimethylamino-N-methyl-4-stilbazolium tosylate (DAST) have been proposed and investigated. The characteristics of the switch waveguide are analyzed. The finite-difference time domain simulation results reveal that the structure can operate as an optical switch by controlling the voltage V-1 or V-2 applied on the region filled with the DAST material with the pi phase shift voltage as V-pi = 2.9 V. The structure has a small dimension of hundreds of nanometers. (C) 2011 American Institute of Physics. [doi:10.1063/1.3614521]
