Strong light confinement of tunable resonances in low symmetric quasicrystal through orientational variations
We propose octagonal quasi-crystal designs providing effective light confinement for different resonance frequencies through the structural modification with the utilization of low-symmetric photonic unit cells. The effect ...
Theoretical and experimental study on surface modes of low symmetric periodic structures
(IEEE Computer Society, 2017-09)
In this study, surface waves supported at the boundary of two-dimensional all dielectric low-symmetric periodic structures (LSPS) are numerically investigated and experimentally verified in the microwave region. In LSPSs ...
Backward propagation of surface slow light in photonic crystals through morphological diversity
We propose and demonstrate photonic crystals (PCs) providing backward-directional propagation of surface slow waves, which is significant for potential PC-based photonic applications. An effective pathway for backward ...
Optical modulators and biochemical sensors based on low-symmetric nanophotonic structures with interferometric configurations
Low-symmetric photonic crystals (PCs) have a high level of tunability in terms of their iso-frequency contours or refractive indices via angular orientations as well as spatial variations of unit cell elements. This ...
Crossed chiral band approximation for wide-band self-collimation of light
(Institute of Physics Publishing, 2020-04)
We propose a perspective to the evaluation of the wide bandwidth phenomenon for low-symmetric photonic structures, by introducing the band tailoring and chiral band approximation on the self-collimation effect. In the case ...
