Output multichannel optical filter based on hybrid photonic quasicrystals containing a high-Tc superconductor

摘要

In this study, we determined the properties of one-dimensional photonic quasicrystals (PQC), including superconductors and dielectric materials, based on two representative quasiperiodic sequences comprising the generalized Thue-Morse (GTM) and generalized Fibonacci sequences in order to design a multichannel optical filter. By using the transfer matrix method and two-fluid model, we determined that the transmittance spectra exhibited a series of photonic band gaps (PBGs). In order to improve the characteristics of the PBGs, we considered the GTM configuration and applied a deformation comprising y = x(h+1 )along the PQC device, where h represents the deformation degree, and x and y are the thicknesses of the layers before and after deformation, respectively.
