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 ...
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 ...
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 ...
