Abstract
Photonic crystals are optical materials with repeating structures that have specific filtering characteristics, among other properties. The impact of materials, periodicity, and thickness of one-dimensional photonic crystal layer on modeling of light is analyzed using Comsol simulations which are based on Finite Element Method (FEM). The influence on the behavior of light transmission characteristics by breaking the periodicity is also observed. In this paper, narrow transmission of photons selectively in the range 311–313 nm is obtained by appropriate inclusion of defect. And also blockage of remaining Ultra Violet (UV) radiation is attained. Phototherapy requires this radiative property for the treatment of Psoriasis. Photonic crystal as a protective shield for psoriasis phototherapy to make it safe and effective is proposed in this paper.
