In the development of topological photonics, achieving three dimensional topological insulators is of significant interest since it enables the exploration of new topological physics with photons, and promises novel photonic devices that are robust against disorders in three dimensions. Previous theoretical proposals towards three dimensional topological insulators utilize complex geometries that are challenging to implement. Here, based on the concept of synthetic dimension, we show that a two…

Realization of a three-dimensional photonic topological insulator

A three-dimensional photonic topological insulator is presented, made of split-ring resonators with strong magneto-electric coupling, which has an extremely wide topological bandgap, forbidding light propagation.

Photonic topological insulator in synthetic dimensions

A spatially oscillating two-dimensional waveguide array is used to realize a photonic topological insulator in synthetic dimensions with modal-space edge states, unidirectionality and robust topological protection.

Photonic quadrupole topological phases in zero-dimensional cavity with synthetic dimensions

Quadrupole topological insulator, which supports robust corner states, has been recently demonstrated in two-dimensional (2D) spatial lattices. Here, we design the first photonic quadrupole

Photonic topological insulator induced by a dislocation in three dimensions

The hallmark of topological insulators (TIs) is the scatter-free propagation of waves in topologically protected edge channels1. This transport is strictly chiral on the outer edge of the medium and

Quantized Hall Conductance of a Single Atomic Wire: A Proposal Based on Synthetic Dimensions

We propose a method by which the quantization of the Hall conductance can be directly measured in the transport of a one-dimensional atomic gas. Our approach builds on two main ingredients: (1) a

Synthetic dimension in photonics

The basic concepts of synthetic dimension in photonics are discussed, and the various approaches towards demonstrating such synthetic dimension for fundamental physics and potential applications are highlighted.

The physics of a photonic structure is commonly described in terms of its apparent geometric dimensionality. On the other hand, with the concept of synthetic dimension, it is in fact possible to

Three-dimensional photonic topological insulator induced by lattice dislocations

We experimentally demonstrate three-dimensional photonic topological insulators induced by lattice dislocations. We observe topological protected surface states, as well as light propagating
