Abstract

In the present paper, we study one-dimensional superconductor photonic crystal composed of dielectric-superconductor multilayers. We use a well-known transfer matrix method approach to calculate transmission spectra. The optical allowed states between two photonic bandgap region is investigated as an optical multichannel filter application. We enhance our investigation to look at the impact of several factors, including thickness, angle of incidence and number of unit cells, on transmission spectra. The multichannel modes can be tuned with the geometrical parameters along with external parameter as the temperature.
