Photon‐Sphere Modes in Curved Optical Microcavities: A Black‐Hole Analogue Laser

open access: yesAdvanced Science, Volume 13, Issue 28, 18 May 2026.
An optical analogue of a Schwarzschild black hole is realized using curved microcavities that preserve light‐like geodesics. A new family of laser modes confined around the photon sphere is identified alongside conventional whispering‐gallery modes. Analytical theory, numerical simulations, and experiments reveal curvature‐induced confinement, enabling

Halide perovskites in wide‐spectrum photodetection

open access: yesBulletin of the Korean Chemical Society, Volume 47, Issue 5, Page 504-526, May 2026.
Recent advances in perovskite‐based photodetectors (PPDs), phototransistors, and photoconductors are technically discussed in this review. Moreover, the mechanism behind different harvesting processes in perovskite following the energy of photons is explained, where the gamma or x‐rays are ionizing.

Intelligent materials for on‐demand electromagnetic absorption

open access: yesInfoMat, Volume 8, Issue 5, May 2026.
This review introduces an innovative “stimulus‐state‐property” paradigm, facilitating a fundamental transition from static to dynamically intelligent electromagnetic wave absorption (EMWA). The key advancement lies in the synergistic integration of external fields with structurally engineered metamaterials and tunable components.

Thin Maxwellian Virtual Reality Near‐Eye Display Using Holographic Optical Element and Mini‐Fresnel Lens Array

open access: yesJournal of the Society for Information Display, Volume 34, Issue 5, Page 254-263, May 2026.
A thin Maxwellian‐view VR near‐eye display based on a holographic optical element (HOE) is presented. Integrating the HOE with the display panel eliminates the structural gap, achieving an 8‐mm internal spacing. Accommodation‐independent image sharpness is experimentally verified over a 0‐ to 3.3‐D range, mitigating the vergence–accommodation conflict.
