Modulational instability and frequency combs in WGM microresonators with backscattering
Nikita M. Kondratiev, Valery E. Lobanov
We introduce the first principle model describing frequency comb generation in a WGM microresonator with the backscattering-induced coupling between the counter-propagating waves.…
Dynamics of soliton self-injection locking in a photonic chip-based microresonator
Andrey S. Voloshin, Nikita M. Kondratiev, Grigory V. Lihachev +6
Soliton microcombs constitute chip-scale optical frequency combs, and have the potential to impact a myriad of applications from frequency synthesis and telecommunications to astro…
Frequency combs in a microring optical parametric oscillator
Alberto Villois, Nikita M. Kondratiev, Ingo Breunig +2
We report the soliton frequency comb generation in microring optical parametric oscillators operating in the down-conversion regime and with the simultaneous presence of the $χ^{(2…
Generation and dynamics of solitonic pulses due to pump amplitude modulation at normal group velocity dispersion
Valery E. Lobanov, Nikita M. Kondratiev, Artem E. Shitikov +2
We studied generation and dynamics of solitonic pulses, platicons, at normal group velocity dispersion due to the pump amplitude modulation. We proposed, that if the required frequ…
