A mathematical shape famous for covering a surface without ever repeating has revealed an unexpected ability to twist light into unusual chiral patterns. The discovery could lead to new ways of ...

Characterized by large aperture and long focal length, the reflective optical system has the advantages of small number of optical elements and simple optical structure. But the intrinsic aberration ...

Photonic Dirac cone is a special kind of degenerate state with linear dispersion, which is ubiquitous in various two-dimensional photonic crystals. By introducing the spatial inversion symmetry ...
