Mode locking by phase-sensitive amplification
Francesco De Lucia, Yifan Sun, Georges Semaan +4
Mode locking is the mechanism by which lasers organize many optical modes into stable trains of ultrashort pulses. It underpins optical frequency combs, precision timing and spectr…
Collective-Coordinate Fluctuations of Driven-Dissipative Solitons
Yifan Sun, Thomas Bunel, Sofya Glazyrina +5
Fluctuations of nonequilibrium localized waves are shaped not only by direct stochastic forcing but also by deterministic transfer among coupled collective degrees of freedom. We d…
Temporal soliton generation in an ultra-high-effective-Q Kerr resonator enabled by Raman gain
Georges Semaan, Yifan Sun, Nicolas Englebert +2
We demonstrate temporal pattern formation in a coherently driven fiber ring cavity whose effective finesse is continuously reconfigured using distributed Raman amplification. We ac…
Parametrically driven Kerr temporal soliton crystals
Yifan Sun, Clément Dupont, Edem Kossi Akakpo +4
We theoretically investigate the dynamics of parametrically driven soliton crystals (PDSC) and their associated frequency combs in doubly resonant cavities with quadratic and cubic…
