Photonic Crystal Cavity-Based Intensity Modulation for Integrated Optical Frequency Comb Generation

Photonic Crystal Cavity-Based Intensity Modulation for Integrated Optical Frequency Comb Generation

A simple scheme to generate an integrated, nanoscale optical frequency comb (OFC) is numerically studied. In this study, all optical intensity modulators based on photonic crystal (PhC) cavities are cascaded both in series and parallel. By adjusting the modulation parameters, such as the repetition...
