Abstract
In this study 1 × 4 optical splitter has been designed for TE-polarized light. The design comprises of 2D Hexagonal lattice where elliptical Si-rods are arranged in the air. Power splitting device with four outputs (1 × 4) has been designed and simulated with Y-Junction. Finite Difference Time Domain (FDTD) method was used for carrying out the simulations and testing of splitting properties of the beam splitter was done. The band gap of the structure was realized through the Plane Wave Expansion (PWE) band solver simulator. The overall size of the 2D Y-junction splitter device designed is 21 μm * 15 μm. The objective was to attain equal power at each output channel with the least amount of loss. The losses were measured at each port and were calculated to be −6.02 db. Three band gaps were measured and their gaps were calculated as 0.20382, 302364; 0.397845, 0.513458; 0.540259, 0.548335 with the tolerance as 0.001.
