Inter-Channel Crosstalk in Periodically Poled LiNb0 3 Waveguides Wavelength Converters

We study experimentally and theoretically the limits of multi-channel parametric wavelength conversion imposed by pump-depletion, in periodically poled LiNbQ3 waveguides. Up to 55 channels with 6dBm of power each, can be simultaneously converted with less than 10-9 error rate using a pump power of 20dBm.
