Laser &Photonics Reviews, EarlyView.This paper demonstrates a snapshot 5D and modality‐switchable lensless camera (Diffuser‐mCam), which can encode 2D intensity, multi‐spectral, polarization, and time information into a monochromatic raw data, and subsequently decode it using the compressed sensing algorithm at the sampling rate of 2.5% per channel.

Laser Stabilized to a Fiber Interferometer With Close‐To‐Zero Temperature Sensitivity
Laser &Photonics Reviews, EarlyView.A laser stabilized to a hollow‐core fibre interferometer is presented. The interferometer is designed to have near‐zero temperature phase‐sensitivity. Laser stabilized to this interferometer put in a non‐vacuum environment achieves ±550 kHz frequency variation over 100 h and an Allan deviation of 2 × 10−14τ, which is comparable to miniature ULE ...

Laser &Photonics Reviews, EarlyView.A compact and low insertion loss programmable photonic circuit is demonstrated based on a 7‐cell hexagonal waveguide mesh with a large free spectral range (FSR) of 31 GHz for a 6‐gate ring resonator configuration. Vernier rings and a dual‐injected ring configuration are demonstrated on this circuit with a further improved FSR of 93 GHz.

NIR/VIS Dual‐Comb Spectroscopy Comparing High and Low Repetition Rate Regimes
Laser &Photonics Reviews, EarlyView.This work compares dual‐comb spectroscopy at lower and higher repetition rates, emphasizing the inherent trade‐off between spectral and temporal resolution. The 80 MHz system provides high‐resolution spectra suitable for analyzing complex molecular structures, whereas the free‐running 1 GHz platform enables fast measurements for real‐time trace gas ...

Bio‐Inspired, Zwitterionic Copolymers with Amphiphilic Character
Macromolecular Rapid Communications, EarlyView.Zwitterionic copolymers based on arginine‐derived monomers are produced by xanthate‐supported photo‐iniferter reversible‐addition‐fragmentation chain‐transfer polymerization. Experiments in relevant conditions show that the designed (co)polymers hardly interact with biologically relevant proteins and enzymes such as bovine serum albumine (BSA), fetal ...

Macromolecular Rapid Communications, EarlyView.Light‐programmable, non‐cytotoxic ion gels based on ABC triblock copolymers undergo photoreversible sol‐gel transitions, crossing the rheological boundary (tan δ ∼ 1). UV–vis light irradiation modulates the lifetime of reversible junctions, switching the scaffold between liquid‐like and solid (gel)‐like states.

Local Field Aperiodic Spectral Power Modulated by Deep Brain Stimulation in Parkinson's Disease
Movement Disorders, EarlyView.Abstract Background Aperiodic spectral broadband power has been described recently as reflecting Parkinson's disease (PD) severity. It has therefore become an increasing focus of research interest in the context of the new adaptive deep brain stimulation (DBS) approach.
