Abstract
We investigated the optical properties of one-dimensional photonic crystal composed of multiple different superconductor materials altogether theoretically by transfer matrix method. The number of Fano resonances generated in transmittance spectra depends on the number of different superconductor materials incorporated in the structure of photonic crystal. The Fano resonances are very sharp and sensitive to the varying parameters. The line profile of multiple Fano resonances in transmission spectra can be tuned by varying the thickness of the layers, the angle of incidence, and the temperature of superconductor photonic crystal. The tunable characteristic of multiple Fano resonances has potential application in bistable optical devices, switches, and sensors.
