Abstract

Disclosed herein are methods, structures, and devices that compensates for modulator loss and modulation inefficiencies introduced by mask misalignments in opposite oriented pn type junction modulators. More specifically, Mach-Zehnder type optical modulators are disclosed wherein both arms in the MZI modulator are arranged in a push-pull configuration and configured to experience pn type junctions of two orientations wherein both arms further configured to experience the same length of waveguide with a pn type junction of each orientation.
