TLDR
In this article, the omnidirectional total reflection range using a binary (BaF2/PbS) periodic structure was enhanced by sandwiching a thin layer of ZrO2 between every two layers, constituting a period of the lattice.Abstract:
Here we demonstrate by theoretical analysis a novel way to enhance the omnidirectional total-reflection wavelength range in one-dimensional photonic bandgap material by using a ternary periodic structure (i.e., three material layers constituting a period of the lattice). The omnidirectional total reflection range using a binary (BaF2/PbS) periodic structure was enhanced by 108 nm when the structure was modified by sandwiching a thin layer of ZrO2 between every two layers, constituting a period of the lattice. A shift of the omnidirectional range toward higher wavelengths was also observed. When the sandwiched layer was CeF3, the enhancement in the range was 120 nm. As the sandwiched layer is very thin, there will not be any significant increase in the size of the reflector, contrary to the case of heterostructured photonic crystals (PCs) where two or more PCs are clubbed together to achieve enhancement.read more

Enhanced refractometric optical sensing by using one-dimensional ternary photonic crystals
TL;DR: One-dimensional ternary photonic crystals are suggested as refractometric sensing elements, for sensing very small refractive index changes of a medium as discussed by the authors, which are not only remarkably smaller, but are also more sensitive than one-dimensional binary photonic crystal based sensing element.

Broad-bandgap and low-sidelobe surface plasmon polariton reflector with Bragg-grating-based MIM waveguide
TL;DR: By optimizing the profile of gap width between the metal and dielectric, the spectral sidelobe ofSPPR is effectively suppressed and thus the performance of the SPPR is further improved.

Design of a tunable optical filter by using a one-dimensional ternary photonic band gap material
TL;DR: In this paper, a band pass filter with a linearly periodic refractive index profile is discussed in analogy with the Kroning Penney model in band theory of solids, and a mathematical analysis is presented to predict allowed and forbidden bands of wavelength with variation of angle of incidence.
