Abstract

An electro-optic (EO) polymer Mach-Zehnder modulator was built with the special feature so that each arm could be modulated independently with a separate 50 Ω microstrip electrode. The design permitted modulation by separate synthesizers at frequencies above the bandwidth of our available detectors. Using this two-tone modulation technique the device was driven at frequencies up to 20 GHz, which is the highest modulation frequency yet reported in an organic EO polymer-based device.
