Linearization of photonic components for digital and analog optical fiber communication systems

Abstract

The need for photonic components with linear electric field has increased for both analog and digital communication systems as these systems evolve toward faster speed, higher spectral efficiency (SE), and wider bandwidth environments. Here, we present a common linearization platform for electric field coming from any Mach-Zehnder (MZ)-based devices. We show how this common platform has applications and advantages as linear Frequency Discriminator (FD) device for phase-modulated direct-detection Microwave Photonic Link (MPLs), and as linear Electric Field Modulator (LOFM) for multilevel coherent transmitter in digital optical communication systems.
