Design of an Optical Power Splitter with Integrated Two-Dimensional Photonic Crystal

摘要

New approach for reducing of the dimensions of Y-branch optical power splitter by using a two-dimensional photonic crystal (PhC) is reported in this paper. Two-dimensional photonic crystal with photonic band gap was designed and simulated by plane wave expansion algorithm (PWE). This optical power splitter was designed for 1.31 μm wavelength range and it is based on Al_xGa_(x-1)As/GaAs material platform. Optical power splitter was designed by RSoft's Photonic Component Design Suite and 3D simulations were performed by beam propagation method (BPM). The PhC implementation with suitable pattern in to Y-branch optical power splitter leads to spread the optical signal on it. It results in sharper division and it is way how to decrease dimensions of optical power splitter. Position of PhC in structure of optical power splitter can change splitting ratio.
