We theoretically demonstrate that the pump's spatial profile can provide a degree of freedom in tailoring at will the nonlinear dynamics and the ensuing spectral content of supercontinuum generation in highly multimoded optical fibers.
We show that a weak Airy pulse can be used to manipulate the dynamics of an optical soliton when propagating at a different wavelength. Our results indicate that an Airy wave packet is considerably more effective in controlling the arrival time of a soliton than a corresponding Gaussian pulse. The nature of these interactions is systematically explored as a function of the initial parameters used...
We demonstrate stable beam self-trapping in soft-matter systems with artificial saturable self-focusing nonlinearities. Our experiments reveal optical beam interactions that can vary from attractive to repulsive as well as an energy exchange.
