Dirac branch-cut modes with relativistic transport
Bofeng Zhu, Chengzhi Ma, Qiang Wang +6
Emergent Dirac fields, exhibiting effective relativistic physics, are most commonly associated with bulk and surface states in materials such as graphene and topological insulators…
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…
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…
Topological Transitions with an Imaginary Aubry-Andre-Harper Potential
Bofeng Zhu, Li-Jun Lang, Qiang Wang +2
We study one-dimensional lattices with imaginary-valued Aubry-Andre-Harper (AAH) potentials. Such lattices can host edge states with purely imaginary eigenenergies, which differ fr…
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…
Single-mode lasing based on PT-breaking of two-dimensional photonic higher-order topological insulator
B. F. Zhu, Q. Wang, Y. Q. Zeng +2
Topological lasers are a new class of lasers that seek to exploit the special properties of topological states of light. A typical limiting factor in their performance is the exist…
Laser Mode Bifurcations Induced by -Breaking Exceptional Points
B. F. Zhu, Q. J. Wang, Y. D. Chong
A laser consisting of two independently-pumped resonators can exhibit mode bifurcations that evolve out of the exceptional points (EPs) of the linear system at threshold. The EPs a…
