Wideband wavelength-flexible all-optical signal regeneration using gain-band tunable Raman amplification and self-phase-modulation-based spectral filtering.
We demonstrate operating wavelength-flexible all-optical signal regeneration with 80 nm wavelength range by simply controlling the pump wavelength of the Raman preamplifier and the passband of broadened signal spectral filtering. In the operating wavelength range, improvements in receiver sensitivity of more than 2.2 dB are successfully achieved.
