All-Optical Reconfigurable-Tunable 1×N Power Splitter Using Soliton Breakup

In this paper, we numerically simulated a glass-based all-optical 1×N power splitter with eleven different configurations using soliton breakup in a nonlinear medium. It is shown that in addition to reconfigurability of the proposed splitter, its power splitting ratio is tunable up to some extent values too. Nonlinear semivectorial iterative finite difference beam propagation method (IFD-BPM) with inclusion of two photon absorption (TPA) effects is applied to simulate the soliton propagation at different mode power. It is shown that operation of the proposed splitter depends on input mode power and an all-optical reconfigurable-tunable functional device is designed with nonlinear optical (NLO) property of a simple structure.
