All-optical wavelength conversion of D(Q)PSK signals in transparent optical networks

Abstract

We will present techniques for all-optical wavelength conversion of phase-modulated signals using four-wave mixing and supercontinuum generation. Techniques for the improvement of the conversion efficiency will be studied. Mainly the suppression of Brillouin scattering and its impact on phase-distortions will be discussed. An assessment of its cascadability in transparent optical networks will conclude the contribution.
