Abstract:

We have theoretically and experimentally investigated the dynamics of frequency comb generation in silicon-based microresonators. In this system, the parametric gain associated with the nonlinear process of four-wave mixing leads to parametric oscillation and generation of signalidler sidemodes. This report describes our results that further develop the parametric comb technology. We theoretically investigate comb generation and modelocking dynamics, and the connection to concepts of synchronization and self-organization. We also investigated mode-crossings in microresonators and tunable coupling, and their impact on comb formation. We studied comb generation without an external pump laser. In addition, we explored comb generation at other pump wavelengths using dispersion engineering. Finally, we investigated comb generation via coherent supercontinuum generation in silicon nitride waveguides.
