Abstract :
A 40-Gb/s wavelength converter based on cross-phase modulation in a dispersion-shifted fiber has been investigated through pulse measurements and simulation. The most important parameter is the dispersive walkoff, which makes the required input power wavelength dependent and determines the optical bandwidth. Simulations show the feasibility of the 160-Gb/s operation by using 2-ps pulses and a highly nonlinear dispersion-shifted fiber.
