Multiple-Band Bit-Level Switching in Two-Pump Fiber Parametric Devices

We investigate 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 30 dB.
