Multichannel Wavelength Conversion Using Fourth-Order Soliton Decay

In this paper, we present the decaying behavior of a fourth-order temporal soliton, which propagates through optical fibers with various dispersion profiles, using the symmetrized split-step Fourier method. We use these behaviors to design two types of 1 times 4 and on 1 times 5 channel wavelength converters using three different types of dispersion profiles along the optical fibers. We also demonstrate that under certain conditions one can use one of the 1 times 4 converters for a pulse train with duration of 30 ps.
