Optofluidic light routing via analytically configuring streamlines of micro-flow
R. Yan, Y. Yang, X. Tu +3
Transformation optics (TO) is a new method to design metamaterials that can manipulate electromagnetic fields. Inspired by the traditional TO techniques which is mostly based on th…
Topological phase transition induced by modulating unit cells in photonic Lieb lattice
Zhi-Kang Xiong, Y. Liu, Xiying Fan +1
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.…
Topological valley crystals in a photonic Su-Schrieffer-Heeger (SSH) variant
Z. Yu, H. Lin, R. Zhou +5
Progress on two-dimensional materials has shown that valleys, as energy extrema in a hexagonal first Brillouin zone, provides a new degree of freedom for information manipulation.…
Higher-order valley vortices enabled by synchronized rotation in a photonic crystal
R. Zhou, H. Lin, Y. Wu +4
Synchronized rotation of unit cells in a periodic structure provides a novel design perspective for manipulation of band topology. We then design a two-dimensional version of highe…
Topological edge states of Kekulé-type photonic crystals induced by a synchronized rotation of unit cells
R. Zhou, H. Lin, Y. Liu +4
Generating and manipulating Dirac points in artificial atomic crystals has received attention especially in photonic systems due to their ease of implementation. In this paper, we…
