Abstract
An optical Mach Zehnder modulator is described. The optical Mach Zehnder modulator may comprise a plurality of segments separated by curved waveguides. For example, an optical Mach Zehnder modulator may comprise a first waveguide arm having a first pn-junction formed therein, a second waveguide arm having a second pn-junction formed therein, a third waveguide arm coupled to the first waveguide arm via a first curved waveguide and a fourth waveguide arm coupled to the second waveguide arm via a second curved waveguide. The segments may have the same polarities. Alternatively, the segments may have opposite polarities. The different segments may be driven using different RF signals. The RF signals may be delayed from one another.
