Abstract

The proposed work presents the design of a photonic crystal structure based on silicon with a square lattice arrangement. It probes the effect of pressure variation on the photonic bandgap and midgap wavelength of the structure. The photonic crystal structure shows a bandgap for the TM mode. The variation in the refractive index of silicon with pressure is utilized to study the bandgap characteristics of the structure with a change in applied pressure. It is observed that the midgap wavelength varies linearly with variations in pressure. This linear variation indicates the application of the proposed structure as a pressure sensor.
