Geometric Filterless Photodetectors for Mid-infrared Spin Light
Jingxuan Wei, Yang Chen, Ying Li +5
Free-space circularly polarized light (CPL) detection, requiring polarizers and waveplates, has been well established, while such spatial degree of freedom is unfortunately absent…

Reconfiguring colours of single relief structures by directional stretching
Qifeng Ruan, Wang Zhang, Hao Wang +7
Colour changes can be achieved by straining photonic crystals or gratings embedded in stretchable materials. However, the multiple repeat units and the need for a volumetric assemb…

Breaking Anti- Symmetry by Spinning a Resonator
Huilai Zhang, Ran Huang, Sheng-Dian Zhang +4
Non-Hermitian systems, with symmetric or antisymmetric Hamiltonians under the parity-time () operations, can have entirely real eigenvalues. This fact has led to surp…
