Abstract

A Mach-Zehnder waveguide modulator comprising a left arm including a left SiGe optical waveguide, and a right arm including a right SiGe optical waveguide; wherein each of the left and right optical waveguides comprises a junction region and a plurality of electrodes for providing a bias across the junction to enable control of the phase of light travelling through the junction regions via dispersion.
