Abstract:
We examine the dynamical behavior of light pulses displaying a soliton-like behavior, but which are affected, when entering a fiber-optic waveguide, by a slight perturbation of profile as compared to the stationary profile in the waveguide. We show that, surprisingly, certain pulses propagate while emitting a radiation whereas other pulses emit no radiation. A physical explanation of this difference of behavior is proposed, and tools of prediction of the radiating or non-radiating character of a light pulse in fiber-optic waveguides, are set up.
