基于光纤光学视界的暗孤子与探测波非线性相互作用调控研究OA

This study investigates the nonlinear interaction at an optical horizon between a dark soliton in the normal dispersion regime of an optical fiber and a weak probe pulse in the anomalous dispersion regime.By numerically solving the generalized nonlinear Schrödinger equation,this paper reveals the control effects of probe parameters on the collision dynamics,energy transfer,and soliton property evolution.A controllable conversion between gray and black solitons was achieved,accompanied by the observation of dispersive wave trapping.The study confirms that a dark-soliton trap,composed of a pair of dark solitons,can serve as a black-hole/white-hole analogue;its high sensitivity to the probe pulse offers a new concept for all-optical device design.
