Abstract
In this paper, we theoretically study the optical properties of a one-dimensional photonic crystal composed alternating semiconductor (GaAs) and superconductor (HgBa2Ca2Cu3O8+δ) layers using the transfer-matrix method and the two-fluid model. Further, we consider that the dielectric constants of both the materials are dependent on the hydrostatic pressure. The results of the simulations clearly reveal that the cutoff frequency may be manipulated through the thicknesses, pressure, and operating temperature of the constituent materials. By increasing temperature while maintaining constant thickness and pressure, the cutoff frequency shifts to lower frequency regions. However, the thickness of the GaAs layers decreases and the cutoff frequency noticeably shifts to higher frequency regions with increasing pressure and thickness of the superconducting layer. In addition, we report the appearance of new photonic band gaps in the transmittance spectrum with the increasing thickness of the GaAs layers.
