Linearization and Reduction of Modulated Optical Insertion Loss for Quadrature Optical Modulator

摘要

An optical Mach-Zehnder superstructure modulator and method that can simultaneously linearize in-phase and quadrature components of optically modulated optical signals and reduce the modulated optical insertion loss (MOIL) by in-phase addition of the in-phase and quadrature components of an amplitude and/or phase modulated optical signal using two high-speed phase modulators embedded in the optical Mach-Zehnder superstructure modulator.
