Abstract

In this work, we report on the emergence of a photonic Hall effect (PHE) system within a narrow filtered background of a one-dimensional defective optical dielectric structure with graphene under the static QHE regime. It is observed that at low temperature and relatively strong applied magnetic fields, electromagnetic defective transmission spectra corresponding to the two decoupled right- and left-handed polarized modes possess a step-like transmission feature which are referred to as "quantum Hall defect modes" (QHD modes or QHDs) in this paper. Tunable growing transitional transmission steps for QHDs with increasing the magnetic field intensity was shown to be possible. Observation of sensitive magneto-transmission oscillations to the thermal excitations in the last plateaus with slow ascending toward unity is another special feature noted in this work. The results of this study which is carried out based on a rapid standard calculations for transfer matrix approach is supplied with commercial simulations marking the first PHE system promise an proper candidate for new photonic applications, especially new tunable magneto-based lenses and photonic magneto-thermal sensors.
