In this work, we theoretically calculate the transmittance spectra for a one-dimensional photonic quasicrystal composed of a high-temperature superconductor and a semiconductor. The materials are organized based on the Octonacci sequence; in addition, we consider the dependence of dielectric constants and layer thicknesses on the applied pressure. When the temperature increases, the transmittance spectra shift toward shorter frequencies, coupled with a decrease in the cutoff frequency at different Octonacci sequence values. When the pressure increases, the layer thicknesses of the materials decrease, bringing about a shift toward higher transmittance spectra and cutoff frequencies. We also noticed that an increase in the layer thickness results in the maximization and emergence of new photonic band gaps.

具有 Octonacci 序列的一维光子准晶体中截止频率的行为
在这项工作中,我们从理论上计算了由高温超导体和半导体组成的一维光子准晶的透射光谱。材料是根据 Octonacci 序列组织的;此外,我们考虑了介电常数和层厚度对施加压力的依赖性。当温度升高时,透射光谱向更短的频率移动,同时在不同的 Octonacci 序列值下截止频率降低。当压力增加时,材料的层厚度会减少,从而导致向更高的透射光谱和截止频率移动。我们还注意到层厚度的增加导致新光子带隙的最大化和出现。
