Topological Directional Coupler
Yandong Li, Minwoo Jung, Yang Yu +3
Interferometers and beam splitters are fundamental building blocks for photonic neuromorphic and quantum computing machinery. In waveguide-based photonic integrated circuits, beam-…
Exact Higher-order Bulk-boundary Correspondence of Corner-localized States
Minwoo Jung, Yang Yu, Gennady Shvets
We demonstrate that the presence of a localized state at the corner of an insulating domain is not always a predictor of a certain non-trivial higher-order topological invariant, e…
Application of Jordan Decomposition to Non-Hermitian Lattice Models with Spectrally-Isolated Lower Dimensional States
Yang Yu, Minwoo Jung, Gennady Shvets
When analyzing non-Hermitian lattice systems, the standard eigenmode decomposition utilized for the analysis of Hermitian systems must be replaced by Jordan decomposition. This app…
A Topology-Controlled Photonic Cavity Based on the Near-Conservation of the Valley Degree of Freedom
Yandong Li, Yang Yu, Fengyu Liu +2
We demonstrate a novel path to localizing topologically-nontrivial photonic edge modes along their propagation direction. Our approach is based on the near-conservation of the phot…
Topologically Protected Photonic Modes in Composite Quantum Hall/Quantum Spin Hall Waveguides
Shukai Ma, Bo Xiao, Yang Yu +3
Photonic topological systems, the electromagnetic analog of the topological materials in condensed matter physics, create many opportunities to design optical devices with novel pr…
