Nonlinear topological photonics has been attracting increasing research interest, as it provides an exciting photonic platform that combines the advantages of active all-optical control offered by nonlinear optics with the unique features of topological photonic systems, such as topologically-protected defect-immune light propagation. In this paper, we demonstrate that topological interface modes and trivial edge modes of a specially designed graphene metasurface can be coupled in a tunable and… 



Robust topologically protected transport in photonic crystals at telecommunication wavelengths

It is shown that the transmittances are the same for light propagation along a straight topological interface and one with four sharp turns, which quantitatively demonstrates the suppression of backscattering due to the non-trivial topology of the structure.

Nonlinear one-way edge-mode interactions for frequency mixing in topological photonic crystals

Topological photonics aims to utilize topological photonic bands and corresponding edge modes to implement robust light manipulation, which can be readily achieved in the linear regime of

Two-dimensional topological photonics

Originating from the studies of two-dimensional condensed-matter states, the concept of topological order has recently been expanded to other fields of physics and engineering, particularly optics

Topological valley plasmon transport in bilayer graphene metasurfaces for sensing applications.

A bilayer graphene metAsurface that possesses plasmonic topological valley interface modes when the mirror symmetry of the metasurface is broken by horizontally shifting the lattice of holes of the top layer of the two freestanding graphene layers in opposite directions is introduced.

Applications of Topological Photonics in Integrated Photonic Devices

Topological photonics is an emerging field of research, which is inspired by the discovery of topological insulators. The introduction of topology endows traditional photonic systems with brand new

Observation of Floquet solitons in a topological bandgap

This work experimentally observed solitons—waves that propagate without changing shape as a result of nonlinearity—in a photonic Floquet topological insulator, and exhibited distinct behavior in that they executed cyclotron-like orbits associated with the underlying topology.

Lattice topological edge and corner modes of photonic crystal slabs

Surface lattice modes, generated by the evanescent coupling between localized modes of optical resonators arranged in a two-dimensional (2D) array, generally exhibit remarkable optical response

Edge Solitons in Nonlinear-Photonic Topological Insulators.

It is shown theoretically that a photonic topological insulator can support edge solitons that are strongly self-localized and propagate unidirectionally along the lattice edge, and using soliton collisions for optical switching.

A silicon-on-insulator slab for topological valley transport

This work realizes topologically protected, robust and unidirectional coupling as well as optical transport on a silicon-on-insulator platform by exploiting the valley degree of freedom, and shows the prototype of robustly integrated devices.

Ultrafast optical tuning of a superprism effect in nonlinear photonic crystals

A comprehensive analysis of an optically tunable superprism effect in a two-dimensional nonlinear photonic crystal is presented. We demonstrate that, under certain circumstances, if one modifies the
