Analysis of waveguides coupling in Photonic Crystal Power-Splitter
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2014, Vol 8, Issue 9
Abstract
In this paper, we suggest a new power-splitter in two-dimensional photonic crystals which can be used for photonic integrated circuits. The proposed power-splitter mechanisms is similar to three-waveguide directional couplers and uses coupling between the states guided with Line defect waveguides. The input waveguide is divided into an image with two folds (two upper and lower waveguides). A photonic crystals power-splitter has been designed with FDTD method. Creation of coupling region in photonic crystal structure causes the wave to be coupled in this region and be transferred to the upper and lower waveguide and to have almost equal transmitted wave in two outputs A and B. in this way, the transmission rate can be reduced in input branch and wave can be equally transferred to upper and lower waveguides with almost equal transmission rate.
