Tuning of transmittance spectrum in a one-dimensional superconductor-semiconductor photonic crystal

摘要

Using, the two-fluid model and the transfer matrix method, we study transmittance spectrum of a one-dimensional photonic crystal made up of alternated layers of a semiconductor (GaAs) and a high-T(c )superconductor (HgBa2Ca2Cu3O8+delta) under the effects of temperature, hydrostatic pressure and angle of incidence. We found that increasing the temperature and the angle of incidence, maintaining pressure and materials thickness constant, there is a shift of the transmittance spectrum to lower frequency values, with a bandwidth increase of the photonic gaps and a decrease in the cutoff frequency. In addition, shifting the transmittance spectrum to higher frequency values and the appearance of new photonic gaps varies with hydrostatic pressure and the angle of incidence, maintaining constant temperature, pressure and materials thickness.
