Periodic and quasi-periodic one-dimensional extrinsically magnetized photonic crystals with robust photonic bandgaps.

Abstract

The study of light wave transmission spectra for a one-dimensional extrinsic multilayered photonic structure is investigated by using the transfer matrix method. The photonic transmission properties of the proposed structure are analyzed for the different values of the external magnetic field, incident angles in terms of standard and oblique, and the electron concentrations of the electromagnetic wave propagation through the extrinsic quasi-periodic and periodic photonic structures. Robust and wider PBGs have appeared for several kinds of quasi-sequences. The increase in electron concentration strengthens the PBG, though it is highly affected by the collision frequency. Furthermore, various PBGs in the terahertz frequency ranges are significantly influenced by the physical entities. The terahertz region's optical bandpass filters can be fabricated using the proposed framework. We also demonstrate that this proposed quasi-periodic multilayered architecture can be supplely controllable photonic crystals with positionable versions of the aforementioned features.
