Observation of non-Hermitian topological disclination states and charge fractionalization
Ruifeng Li, Rimi Banerjee, Subhaskar Mandal +8
There has been significant interest in exploring topological disclination states, which effectively probe the band topology of the host material beyond the conventional bulk-edge c…
Topological photonic crystal fibre
Bofeng Zhu, Kevin Hean, Stephan Wong +8
Photonic crystal fibres (PCFs) are optical fibres that guide light using a modulated dielectric medium. They provide an exceptionally versatile platform for various applications, t…
Momentum flatband and superluminal propagation in a photonic time Moiré superlattice
Linyang Zou, Hao Hu, Haotian Wu +4
Flat bands typically describe energy bands whose energy dispersion is entirely or almost entirely degenerate. One effective method to form flat bands is by constructing Moiré super…
Versatile Braiding of Non-Hermitian Topological Edge States
Bofeng Zhu, Qiang Wang, You Wang +2
Among the most intriguing features of non-Hermitian (NH) systems is the ability of complex energies to form braids under parametric variation. Several braiding behaviors, including…
On-chip Amorphous THz Topological Photonic Interconnects
Rimi Banerjee, Abhishek Kumar, Thomas Tan Caiwei +6
Valley Hall photonic crystals (VPCs) offer the potential to create topological waveguides capable of guiding light through sharp bends on a chip. They can seamlessly integrate with…
Non-Hermitian Photonic Lattices: tutorial
Qiang Wang, Y. D. Chong
Non-Hermitian photonic lattices combine the peculiar consequences of energy non-conservation with the physics of bandstructures, giving rise to a variety of exotic properties not f…
Continuum of Bound States in a Non-Hermitian Model
Qiang Wang, Changyan Zhu, Xu Zheng +3
In a Hermitian system, bound states must have quantized energies, whereas extended states can form a continuum. We demonstrate how this principle fails for non-Hermitian systems, b…
Anomalous single-mode lasing induced by nonlinearity and the non-Hermitian skin effect
B. F. Zhu, Q. Wang, D. Leykam +3
Single-mode operation is a desirable but elusive property for lasers operating at high pump powers. Typically, single-mode lasing is attainable close to threshold, but increasing t…
Amorphous photonic topological insulator
Peiheng Zhou, Gui-Geng Liu, Xin Ren +6
Photonic topological insulators (PTIs) exhibit robust photonic edge states protected by band topology, similar to electronic edge states in topological band insulators. Standard ba…
Observation of valley Landau-Zener-Bloch oscillations and pseudospin imbalance in photonic graphene
Yong Sun, Daniel Leykam, Stephen Nenni +4
We demonstrate inter-valley Bloch oscillation (BO) and Landau-Zener tunneling (LZT) in an optically-induced honeycomb lattice with a refractive index gradient. Unlike previously ob…
