Laser &Photonics Reviews, EarlyView.Nonlocal leaky mode metasurfaces reconstruct multiplexed holograms directly from unfiltered thermal light. High‐Q leaky guided modes compress broadband halogen emission into narrowband channels, enhancing temporal coherence a hundredfold, while a single nanohole array encodes independent images addressed by mode, angle, and polarization, establishing ...

Laser &Photonics Reviews, EarlyView.Oblique metallization creates one‐sided opaque metagratings that route zero‐order‐hidden optical power between nonzero diffraction and material dissipation. Cross‐sectional‐SEM‐guided models reproduce measured zero‐order spectra and reveal direction‐selective channel exchange governed by morphology and Rayleigh‐order availability.

Laser &Photonics Reviews, EarlyView.Electrically contacted circular Bragg grating resonators incorporating InGaAs quantum dots directly grown on silicon enable bright, telecom O‐band single‐photon emission with wide‐range electrical tuning. A record quantum‐confined Stark shift of 16 nm is combined with high photon extraction efficiency, excellent single‐photon purity > 99.9%, and robust

Small, EarlyView.This study visualizes the long‐term aging of lateral MoS2‐WS2 heterostructures stored under low‐vacuum condition using hyperspectral phase microscopy (HPM). While conventional techniques show limited sensitivity to ultrathin and amorphous oxidation products, HPM successfully reveals morphological and optical changes during aging. Optical modeling using

Polarization properties of interferometrically interrogated fiber Bragg grating and tandem-interferometer strain sensors [PDF]
, 2006 Lead sensitivity in low-coherence interferometric fiber-optic sensors is a well-known problem. It can lead to a severe degradation in the sensor resolution and accuracy through its effect on the fringe visibility and interferometric phase.

Small, EarlyView.An atomically precise Ag6 nanocluster stores multiple electrons through sequential reduction reactions and releases the stored charge through successive emissive oxidation reactions with a benzoyl peroxide‐derived radical. This multielectron charge storage pathway enables an electrochemiluminescence cascade, producing a substantially more efficient ...

Small, EarlyView.Surface‐enhanced infrared absorption (SEIRA) and Raman scattering (SERS) are complementary, highly sensitive molecular detection methods. A reusable metamaterial substrate capable of combined SEIRA and SERS is used here for real‐time sensing, tracking interfacial dynamics in an electrochemical reaction and detecting symmetry‐breaking behavior at the ...

Ultrafast Coherent Phonon Dynamics in GeTe and GeSe: Contrasting Metavalent and Covalent Bonding
Small, EarlyView.Ultrafast laser measurements reveal the differences in the optical response of atomic vibrations in GeTe and GeSe thin films. While crystalline GeTe exhibits strong, highly excitation‐sensitive coherent vibrations linked to metavalent bonding, covalently bonded GeSe shows weak or absent coherent phonons.
