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.</p> Nonlinear optics, integrated optics, Optical switching devices, Spatial solitons, Ultrafast nonlinear optics. 19 29 http://ijop.ir/browse.php?a_code=A-10-447-1&slc_lang=en&sid=1 Amin Ghadi a.ghadi@umz.ac.ir 10031947532846001506 10031947532846001506 Yes University of Mazandaran Saeed Mirzanejhad saeed@umz.ac.ir 10031947532846001507 10031947532846001507 No University of Mazandaran
