Design of Beam Splitters by Using 1D Defect Ternary Photonic Band Gap Structures

Abstract

In this paper, beam splitters based on 1D defect ternary Photonic crystals are proposed. These beam splitters can split lights of different wavelengths into two beams having 50% of i/p optical power. The 50% of i/p light power of the splitted wavelength will be transmitted by the structure and 50% of i/p light power will be reflected by the structure. These splitted light beams will be available at the o/p and i/p ports, respectively. The wavelength to be splitted by this beam splitter and wavelength range of operation can be changed and controlled by changing the structural parameters.
