TL;DR: This work demonstrates lasing action of corner states in nanophotonic topological structures and identifies several multipole corner modes with distinct emission profiles via hyperspectral imaging and discern signatures of non-Hermitian radiative coupling of leaky topological states.

TL;DR: In this paper, the concept of supercavity mode created by merging symmetry-protected and accidental bound states in the continuum in the momentum space was employed to realize an efficient laser based on a finite-size cavity with a small footprint.

TL;DR: This work demonstrates that the integration of nanoparticle-dispersed capacitor elements into an array readily yields a real-time pressure monitoring application and a fully functional touch device capable of acting as a pressure sensor-based input device, thereby opening up new avenues to establish processing techniques that are effective on the nanoscale yet applicable to macroscopic processing.

TL;DR: Helical topological polaritons are demonstrated up to 200 kelvin without external magnetic field in monolayer WS2 excitons coupled to a nontrivial photonic crystal protected by pseudo time-reversal symmetry.

TL;DR: The generation of BCPs photonic microspheres is presented with 3D periodical concentric lamellar structures through confined self-assembly, demonstrating large reflection wavelength shift under organic solvent permeation and pH adjustment.
