Parametrically Tunable Soliton-Induced Resonant Radiation by Three-Wave Mixing

Hairun Guo

We show that a temporal soliton can induce resonant radiation by three-wave mixing nonlinearities. This constitutes a new class of resonant radiation whose spectral positions are parametrically tunable. The experimental verification is done in a periodical ...
