Abstract
In order to provide a low power duobinary modulator for the long reach 10 Gb/s metro space that is relatively small and relatively inexpensive to make, a method of operating a Multiple Quantum Well (MQW) III-V Mach-Zehnder (MZ) optical modulator to have it provide a high-quality duobinary signal is provided. The method of operating the MQW III-V MZ optical modulator provided by the invention makes possible a high-quality duobinary modulator that has substantially balanced `on` states. That is to say, both duobinary `on` states are characterized by having respective output signals with substantially equivalent: peak intensities; high extinction ratios; and low frequency chirp.
