All-Optical Switching of Supercontinuum Spectra

We discuss an efficient all-optical switching scheme with ultrafast switching times and high switching contrast which satisfies fan-out [1] , one difficult challenge to be met in all optical computing. To this end, a nonlinear interaction mechanism provides a means to control light by light [2] , [3] , realizing switching between different parts of soliton-fission induced supercontinuum spectra. The experimental setup employed a NL-PM-750 photonic crystal fiber (NKT Photonics), and the complementing numerical simulations were performed using a generalized nonlinear Schrödinger equation [1] , [3] .
