Study and Performance Optimization of an Integrated Mach-Zehnder Modulator for Optical Telecommunications

Abstract

The fundamental properties of an optical modulator are theoretically examined in this research using simulation models. The device under study is an active component of integrated optics; it has an interferometer with parallel waveguides and couplers in an S-Bend as its structural components.The Beamprob simulator incorporated into the Rsoft program is employed to continue the performance evaluation of the MZI (Mach Zehnder Inteferometer). Following the application of the polarization voltage, the material in one of the waveguides' arms' nonlinear effects causes a phase shift.The influence of several parameters, such as the length of the arms, the gap (inter-electrode distance), and the coefficient of non-linearity, was presented.We examined how the different output intensities fluctuated in order to use this device for optical modulation so that the area where the signal was most utilized could be identified.
