Experimental realization of photonic topological insulator in a uniaxial metacrystal waveguide.
Photonic analogue of topological insulator was recently predicted by arranging ε/μ (permittivity/permeability)-matched bianisotropic metamaterials into two-dimensional superlattices. However, the experimental observation of such photonic topological insulator is challenging as bianisotropic metamaterial is usually highly dispersive, so that the ε/μ-matching condition can only be satisfied in a ...
متن کاملOne-dimensional helical transport in topological insulator nanowire interferometers.
The discovery of three-dimensional (3D) topological insulators opens a gateway to generate unusual phases and particles made of the helical surface electrons, proposing new applications using unusual spin nature. Demonstration of the helical electron transport is a crucial step to both physics and device applications of topological insulators. Topological insulator nanowires, of which spin-text...
متن کاملSelective infiltration of photonic crystal fibres for waveguide arrays
Photonic crystal fibres (PCFs) can be used as a platform for the study of periodic photonic structures as well as the novel linear and nonlinear physical effects associated with them. The cladding holes in these micro-structured fibres can be infiltrated with a liquid utilising capillary action. This can be prevented in selected holes through the prior blocking of one end, producing periodic ph...
متن کاملPhotonic topological insulator with broken time-reversal symmetry.
A topological insulator is a material with an insulating interior but time-reversal symmetry-protected conducting edge states. Since its prediction and discovery almost a decade ago, such a symmetry-protected topological phase has been explored beyond electronic systems in the realm of photonics. Electrons are spin-1/2 particles, whereas photons are spin-1 particles. The distinct spin differenc...
متن کاملMagnetoresistance oscillations in topological insulator Bi2Te3 nanoscale antidot arrays.
Nanoscale antidot arrays were fabricated on a single-crystal microflake of topological insulator Bi2Te3. The introduction of antidot arrays significantly increased the resistance of the microflake, yet the temperature dependence of the resistance remains metallic. We observed that small oscillations that are periodic in magnetic field B appeared on top of the weak anti-localization magnetoresis...
