Theory and modelling of frequency comb generation in microring resonators

A frequency comb is generated when a single frequency laser beam transforms into a broad spectrum of equally spaced spectral lines (frequency comb) inside a nonlinear device. This process has a variety of practical applications in high precision measurements and optical communications. The phenomenon is accompanied by the generation of a train of ultrashort pulses in the time domain and its understanding can be approached using the methodology of the soliton theory. Goals of this project are to elucidate a role of the soliton dynamics in the frequency comb generation and parametric amplification processes in microring resonators and related nano-photonic setups. Theoretical analyses of bright and dark, scalar and vector solitons, their instabilities and bifurcations, the interaction of solitons with linear waves and between themselves; of the soliton dynamics in systems with the second-order and Raman nonlinearities – are planned to be carried out. These fundamental studies will be further utilized to propose new methods of the manipulation and stabilization of frequency combs. We have a broad network of the theoretical and experimental collaborators in this area giving to the project a strong international dimension.

Applicants will be expected to have an interest and an appropriate background in one or more of the following: computational and nonlinear physics, nonlinear and quantum optics.
