Probe-controlled soliton frequency shift in the regime of optical event horizon

摘要: In optical analogy of the event horizon, temporal pulse collision and mutual interactions are mainly between an intense solitary wave (soliton) a dispersive probe wave. such regime, here we numerically investigate probe-controlled soliton frequency shift as well self-compression. particular, in dispersion landscape with multiple zero wavelengths, bi-directional spectral tunneling effects is possible. Moreover, propose mid-infrared self-compression to generation few-cycle ultrashort pulses, bulk quadratic nonlinear crystals contrast fibers or cubic media, which could contribute community simple flexible method experimental implementations
