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…

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…
