Abstract

We study the interaction between two solitons from different frequency channels in an optical fiber in the presence of third order dispersion (TOD). We find that the amplitude of the emitted radiation is proportional to d₃/Ω², where d₃ is the TOD coefficient and Ω is the inter-channel frequency difference. The source term for this radiation is identical to the one that would be generated by a variation with respect to distance along the fiber of the second order dispersion coefficient.
