Enhancing the performance of a silicon photonic optical modulator using device level engineering

Abstract

The research presented in this thesis deals with enhancing the performance of an optical modulator in Si photonics platform using device level engineering techniques The thesis starts with an introduction to the field of Si photonics followed by a comprehensive theory of modulation techniques and metrics used to characterize the modulation efficiency A chapter on optical waveguides is presented elaborating on determining the waveguide characteristics viz mode loss and dispersion usin...
