P. Ohlen et al., Wavelength dependence and power requirements of a wavelength converter based on XPM in a dispersion-shifted optical fiber, IEEE PHOTON, 12(5), 2000, pp. 522-524
A 40-Gb/s wavelength converter based on cross-phase modulation in a dispers
ion-shifted fiber has been investigated through pulse measurements and simu
lation. The most important parameter is the dispersive walkoff, which makes
the required input power wavelength dependent and determines the optical b
andwidth. Simulations show the feasability of the 160-Gb/s operation by usi
ng 2-ps pulses and a highly nonlinear dispersion-shifted fiber.
