Photonic band gaps of increasingly isotropic crystals at high dielectric contrasts

Photonic band gaps (PBGs) are highly sensitive to lattice geometry and dielectric contrast. Here, we report theoretical and experimental confirmation of PBGs in photonic crystals (PhCs) with increasing levels of structural isotropy. These structures are: a standard 6-fold hexagonal lattice, a locally 12-fold Archimedean-like crystal, a true quasicrystal generated by non-random Stampfli inflation, and a biomimetic crystal based on Fibonacci phyllotaxis. Experimental transmission spectra were obtained at microwave frequencies using high-index alumina (ε = 9.61) rods. The results were compared to FDTD-calculated transmission spectra and PWE-calculated band diagrams. Wide and deep (> 60dB) primary TM gaps present in all high-index samples are related to reciprocal space vectors with the strongest Fourier coefficients. Their mid-gap frequencies are largely independent of the lattice geometry for comparable fill factors, whereas the gap ratios shrink monotonically as structural isotropy increases.

“…As has been proved, the metallic absorption could be reduced, 16 deep forbidden bands could be realized by the redistribution of the displacement field, 17 and high transmission band could be obtained by reducing the metallic absorption losses with the effect of resonant tunneling.

Photonic bands in two-dimensional metallodielectric photonic crystals composed of metal coated cylinders J. Appl. Phys. 106, 033101 (2009); 10.1063/1.3183934 Bragg attenuation length in metallo-dielectric photonic band gap materialsOne-dimensional metallodielectric heterostructural photonic band gap (PBG) material is designed to reach high transmittance band in short wavelength, broad and deep forbidden band in long wavelength, especially sharp cutoff edge between the transmission and forbidden bands. The designed PBG material is applied to modify the emission spectrum of a BaF 2 scintillator and is proved to be adequate to suppress the slow component of the scintillation light. The suppression ratio of the slow to the fast component reaches 28 dB with a tolerable attenuation of the fast component.

“…12) When we introduce defects in different positions of a periodic photonic crystal, the defect modes will be identical as long as the defects are introduced by the same means. However, quasiperiodic photonic crystal [13][14][15][16] (QPC) does not possess translational symmetry. The property of the quasiperiodic photonic crystal may be different from that of the periodic ones.…”

We have analyzed the difference in apparent barrier height (ABH) by the approach and modulation methods, using the boundary-matching scattering-state density functional method, in which electric states under an applied bias voltage are self-consistently calculated. We found that the approach and modulation methods provide nearly the same calculated ABH values for a wide range of tunneling conductances from 10-11 to 10-5 Ω-1. The change in ABH in the tunneling conductance range from 10-11 to 10-7 Ω-1 is smaller than that in the tunneling conductance range from 10-7 to 10-5 Ω-1, suggesting that some of the observed discrepancies between the two methods may be due to the difference in tip-sample distance. Furthermore, we also found that the change in modulation amplitude, which is caused by the force acting on the tip atom due to the applied bias voltage, can account for the observation that the modulation method provides a smaller ABH value than the approach method.
