One-dimensional structure made of periodic slabs of SiO2/InSb offering tunable wide band gap at terahertz frequency range
Transmittance spectra of the single defect 1D-PC consisting of SiO2/InSb alternating layers at different crystal temperatures of T = 225 K, 255 K, 285 K, and 310 K. Panels (b) and (c) are the magnifications of the two PBG areas of the spectra. The incident angle is normal to the crystal and the thicknesses of the layers are 4 μm.
