Excitons in biased bilayer graphene are electrically tunable excitations in the mid‐infrared (MIR) spectrum, where optical transitions are typically scarce. In this work, it is demonstrated that when the bilayer is encapsulated in hexagonal‐boron‐nitride (hBN)—a material supporting optical phonons and hyperbolic‐phonon‐polaritons (HPhPs) in the MIR—the

Chiral Metasurfaces with Multidimensional Tunability for Optical Chiral States
A novel bilayer perovskite chiral metasurface enables tunable transitions between BIC‐associated vortex centres and circularly polarized states via rotational symmetry control. Breaking rotational symmetry and applying in situ rotation to the upper layer allows precise, omnidirectional tuning of C points in momentum space. This evolution forms a Möbius‐

Numerical and Experimental Methods for Estimating the Propagation Loss in Microphotonic Waveguides
Finite‐element finite‐difference time domain, eigenmode‐expansion, and volume‐current simulations are benchmarked against cut‐back, ring‐resonator, and OFDR measurements to quantify waveguide propagation loss in integrated photonic circuits. Scattering, absorption, leakage, and back‐reflection contributions are dissected; error sources are ranked; and ...
