Abstract :
We investigated the feasibility of multiple-band switching using a two-pump fiber parametric device. The switching architecture combines band amplification, wavelength conversion, and selective signal conjugation, enabled by temporal control of one or both parametric pumps. A switching scheme with a single pump control was constructed and evaluated. Multiple-band bit-level optical switching is demonstrated over bandwidth greater than 50 nm, with a maximal conversion efficiency of 24.2 dB.
