Frontiers of Bright CEP‐Stable Broadband Infrared Sources
Laser &Photonics Reviews, EarlyView.Bright CEP‐stable broadband infrared sources push the limits of ultrafast science by delivering exceptional brightness alongside few‐cycle durations and multi‐octave spectral coverage. This review highlights emerging architectures and nonlinear conversion strategies that scale power while preserving phase stability.

Controlling Collective Quasiparticle Dynamics Beyond Decoherence in Topological Interfaces
Laser &Photonics Reviews, EarlyView.Gold nanoparticles placed above a deformed honeycomb plasmonic crystal couple to a chiral topological interface mode. The pseudospin‐split bands ψ+/ ψ− encode spin‐momentum locking, so emitters radiate directionally along the domain wall and share a common phase.

Novel Sulfur‐Rich Polymers from Inverse Vulcanization as Functional Building Blocks for Photonics
Macromolecular Rapid Communications, EarlyView.Isopropenyl aromatic comonomers, in particular novel 2,7‐diisopropenylfluorene and 2,8‐diisopropenyldibenzothiophene, synthesized by sustainable, facile, single‐step SMCCR from available brominated substrates are exploited in the Inverse Vulcanization process to obtain functional Sulfur‐rich macromolecular materials.

Spectroscopic Ellipsometry of Conducting Anisotropic Pedot thin Films
Macromolecular Rapid Communications, EarlyView.We measure the optical response of poly[3,4‐ethylenedioxythiophene] thin films through the combination of polarized photon spectroscopies (variable‐angle ellipsometry, UV–mid‐IR reflectance and transmittance) and wide‐angle X‐ray scattering, revealing anisotropic optical response and conductivity and enabling structural modelling of chain and π‐system ...

Small, EarlyView.A simple incorporation of Zr imparts biodegradability to inherently inert rare‐earth‐based upconversion nanoparticles without compromising optical performance. Surface energy modulation of LiREF4 facets by a binary‐surfactant system enables Zr incorporation during hot‐injection synthesis.

Small, EarlyView.We demonstrate a rational and scalable strategy for the construction of 2D hybrid architecture by the liquid‐phase co‐assembly of graphene and polyaniline nanosheets. A high‐shear mixing process enables face‐to‐face stacking, creating a robust interface with strong electronic coupling.

Light-controlled soft bio-microrobot
Light: Science & ApplicationsMicro/nanorobots hold exciting prospects for biomedical and even clinical applications due to their small size and high controllability. However, it is still a big challenge to maneuver micro/nanorobots into narrow spaces with high deformability and ...

Small, EarlyView.Wafer‐scale top‐down fabrication yields silicon nanoparticles with exceptional uniformity (CV 1.7%–2.4%), enabling deterministic axis‐ratio tuning. At AR ≈$\approx$ 2.1, electric–magnetic dipoles overlap on‐resonance, producing near‐Kerker forward scattering (F/B ≈$\approx$ 12.5).

Quasi‐BIC and Reflective Mode Coupling Drives SHG Beyond the Q Factor Limit
Small, EarlyView.An analytical expression is developed to relate second‐harmonic generation to both the resonance Q factor and absorptance. Simulations and experiments on a dual‐resonance 3R‐MoS2 metasurface validate the formula, showing that absorptance engineering provides an effective route to enhance SHG beyond conventional Q‐only design.
