Band gap and optical transmission in the Fibonacci type one dimensional AB6C7 based photonic crystals

OpenAlex English

Abstract In this work, we present an investigation of the optical properties and band structure calculations for the photonic crystal structures (PCs) based on one‐dimensional (1D) photonic crystal. Here we use 1D A5B6C7(A:Sb; B:S,Se; C:I) based layers in air background. We have theoretically calculated photonic band structure and optical properties of A5B6C7(A:Sb; B:S,Se; C:I) based PCs. In our simulation, we employed the finite‐difference time domain (FDTD) technique and the plane wave expansion method (PWE) which implies the solution of Maxwell equations with centered finite‐difference expressions for the space and time derivatives.
