Abstract

In this study, we calculate the transmittance spectrum of a one-dimensional photonic quasicrystal composed of SiO2 and an extrinsic InSb semiconductor. The layers of materials are arranged as per the Octonacci sequence. When using the transfer matrix method, the transmittance spectrum is tuned, by a variation in the temperature, the doping concentration, and the thicknesses of materials. At fixed values of the Octonacci sequence, we find that the fractal photonic band gap and the quasi-localized states exhibit a shift to higher frequencies when temperature increases. The blue-shift of the transmittance spectrum is obtained when the doping concentration is increased.
