Abstract
Disclosed herein are methods, structures, apparatus and devices that improve the control and/or controllability of a group of Mach-Zehnder Interferometer modulators. Advantageously, such control may be implemented with optical tuning elements shared among all of the modulators, or with separate optical tuning elements operated through the effect of a set of common signals. Accordingly implementations according to one aspect of the present disclosure provides a significantly simplified configuration—where the extinction ratios of all modulators within the group are controlled jointly—in sharp contrast to those configuration(s) wherein all modulators are individually controlled.
