Topological states in photonic systems
نویسندگان
چکیده
Optics played a key role in the discovery of geometric phase. Once again, it joins the journey of exploring topological physics, bringing us bosonic topological states of one-way waveguides, Weyl points and a single surface Dirac cone. At the interfaces of topological photonic materials, the propagation of photons is protected against disorder by the momentum-space topologies in the bulk. Topology equips us with an ability to make perfect photonic devices using imperfect interfaces.

Photonic simulation of topological superconductor edge state and zero-energy mode at a vortex
Photonic simulations of quantum Hall edge states and topological insulators have inspired considerable interest in recent years. Interestingly, there are theoretical predictions for another type of topological states in topological superconductors, but debates over their experimental observations still remain. Here we investigate the photonic analogue of the p(x) + ip(y) model of topological su...
متن کاملProbing topological protection using a designer surface plasmon structure
Topological photonic states, inspired by robust chiral edge states in topological insulators, have recently been demonstrated in a few photonic systems, including an array of coupled on-chip ring resonators at communication wavelengths. However, the intrinsic difference between electrons and photons determines that the 'topological protection' in time-reversal-invariant photonic systems does no...
متن کاملSelf-localized states in photonic topological insulators.
We propose solitons in a photonic topological insulator: self-localized wave packets forming topological edge states residing in the bulk of a nonlinear photonic topological insulator. These self-forming entities exhibit, despite being in the bulk, the property of unidirectional transport, similar to the transport their linear counterparts display on the edge of a topological insulator. In the ...
متن کاملTopologically protected bound states in photonic parity-time-symmetric crystals.
Parity-time (PT)-symmetric crystals are a class of non-Hermitian systems that allow, for example, the existence of modes with real propagation constants, for self-orthogonality of propagating modes, and for uni-directional invisibility at defects. Photonic PT-symmetric systems that also support topological states could be useful for shaping and routing light waves. However, it is currently deba...
متن کاملTopologically protected states in active photonic metamaterials
Background: A topologist is sometimes described as a mathematician who cannot discriminate between a tea cup and a doughnut. This means that topology focuses on global properties such as connectedness instead of geometrical detail, thereby paving the road for a new level of understanding. Topological invariants such as the Euler characteristic for surfaces in R are naturally quantized and do no...
