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 AlxGax-1As/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.
