Design of beam splitters with different beam splitting ratios by using double defect layered 1D ternary photonic band gap structures

In this paper, beam splitters with different beam splitting ratios are designed by using double defect layered 1D ternary photonic band gap (PBG) structures. These beam splitters can split input beam of a light wavelength into two output light beams. One output light beam will be transmitted through the structure and other output light beam will be reflected by the structure. The splitting ratio and the light wavelength to be splitted by these beam splitters can be decided by choosing the structural parameters.
