Construction of near-? multiple chiral exceptional points in momentum space of photonic crystal slabs
Published on 2026-06-03 by Jingyu Zhang, Yang Gao, Tianfu Ma, Wenjia Li, Weimin Ye and Jianlong Liu @IOP SCIENCE
Abstract: Exceptional points (EPs) in optical systems have attracted considerable attention because of their nontrivial topological properties and unusual physical effects. Among them, scattering EPs are particularly appealing for describing chiral response through the scattering matrix. Photonic crystal slabs offer a versatile platform for studying chiral scattering EPs in momentum space, where their topological evolution can be conveniently accessed and engineered. In this work, a convenient approach is[...]
Our summary: This study presents a method to construct multiple chiral exceptional points (EPs) in the momentum space of photonic crystal slabs. The research identifies and analyzes the evolution of these EPs near the Γ point, highlighting their potential for polarization conversion. The findings suggest practical applications for controlling chiral EPs in optical metadevices.

Topological phase transition induced by modulating unit cells in photonic Lieb lattice
Published on 2026-05-12 by Zhi-Kang Xiong, Y Liu (???), Xiying Fan and Bin Zhou @IOP SCIENCE
Abstract: Topological photonics was embarked from realizing the first-order chiral state in gyromagnetic media, but its higher-order states were mostly studied in dielectric lattice instead. In this paper we theoretically unveil a hierarchy of topological phases under broken time-reversal symmetry, which include the first-order Chern, and the second-order dipole, quadrupole phases. Concretely, by relaxing a certain spatial symmetry of unit cell, versatile topological phases including both edge and corner [...]
