PWE approach to MSOF for beam splitting application

Simulation studies for electric field distribution in micro structured optical fiber (MSOF) using plane wave expansion (PWE) technique is reported in this paper, where the outcomes of electric field distribution leads to beam splitting application. Here MSOF is realized by 5 × 5 air holes on silicon substrate with defect at centre. PWE method is employed to envisage a number of spectrally distinct output beams with respect to single input beam. Simulation result revealed that electric field mode of propagation varies nonlinearly with respect to radius of air hoes at lattice constant of 500 nm, for example the proposed MOSF allows 1,2, 3,4,5,6 and 7 number of modes of propagation at radius of air holes of 110 nm,120 nm, 210 nm 150 nm, 162 nm, 165 nm and 230 nm respectively. Finally simulation is also carried out for output power emerging from MSOF. And present result divulges that the power emerging from micro structure fiber depends on both structure parameter and configuration along with nature of material.
