Paper Abstract

In this paper, the band structure for 1-D photonic crystal structure, which is composed of two different dielectric layers in a one-dimensional pattern, obtained by transfer matrix method, is reported. It has been observed that the bandgap depends on the contrast of dielectric constant and thickness of dielectric layers. Further, it is found that the enhanced bandgap can be obtained by changing the dielectric contrast and thickness of the layers. Primary & Secondary bandgaps are also estimated and the bandgaps have been engineered with reference to their dependence on spacing between layers and dielectric contrasts. Further, we also report the band gap calculation of three different dielectric layers stacked in 1-D periodic structure. Such structure might find its application in the design & development of asymmetric planar photonic crystals
