Be. Olsson et al., A simple and robust 40-Gb/s wavelength converter using fiber cross-phase modulation and optical filtering, IEEE PHOTON, 12(7), 2000, pp. 846-848
In this letter, 40-Gb/s return-to-zero data wavelength conversion is demons
trated using cross-phase modulation in an optical fiber with subsequent con
version of phase modulation to amplitude modulation using an optical filter
. The scheme is potentially ultrahigh speed and can be made polarization in
dependent.
