Abstract
The transmission properties of one-dimensional photonic crystal consisting superconducting and dielectric material has been investigated theoretically by transfer matrix method (TMM). The transmission spectra obtained by simulation of superconductor photonic crystal shows Fano resonance line profile. The Fano resonance observed in transmission spectra is the function of the thickness of constituent layers, number of periods, and temperature of superconductor. The maxima and minima of Fano resonance can be changed by varying thickness of superconductor and dielectric layers. Increase in thickness of superconductor layer increases the maxima of Fano resonance towards 100 % transmittance, while minima of Fano resonance tends towards zero transmittance. The gradient between maxima and minima of the Fano resonance decreases with increasing the thickness of the superconductor layer while the gradient of Fano resonance increases with increase in thickness of dielectric layer. Increasing the thickness of dielectric layer decreases the maxima of Fano resonance. The position of Fano resonance can be tuned over a definite frequency range by varying temperature of the superconductor layer.
