Simultaneous inverted and non-inverted wavelength conversions with 2R regeneration based on nonlinear polarization rotation of SOA

Abstract

Simultaneous inverted and non-inverted wavelength conversions (WCs) at 10 Gb/s with 2R regeneration are demonstrated using nonlinear polarization rotation in an SOA. A power penalty reduction of 1.2 dB for inverted WC and 0.8 dB for non-inverted WC is obtained at a BER of 10-9.
