Not Accessible

Your library or personal account may give you access

Abstract

We propose a nonlinear fiber-based optical frequency shifter using two CW pumps orthogonally polarized to signals and demonstrate THz-range error-free frequency shifting of 1.6-Tb/s DP-16QAM WDM signal without guard-band midway through 160 km transmission.
