Observation of spectral self-imaging by nonlinear parabolic cross-phase modulation
journal contribution
posted on 2023-06-09, 01:04 authored by Lei Lei, Jeonghyun Huh, Luis Ramero Cortés, Reza Maram, Benjamin Wetzel, David Duchesne, Roberto Morandotti, José AzañaWe report an experimental demonstration of spectral self-imaging on a periodic frequency comb induced by a nonlinear all-optical process, i.e., parabolic cross-phase modulation in a highly nonlinear fiber. The comb free spectral range is reconfigured by simply tuning the temporal period of the pump parabolic pulse train. In particular, undistorted FSR divisions by factors of 2 and 3 are successfully performed on a 10 GHz frequency comb, realizing new frequency combs with an FSR of 5 and 3.3 GHz, respectively. The pump power requirement associated to the SSI phenomena is also shown to be significantly relaxed by the use of dark parabolic pulses. (C) 2015 Optical Society of America
