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 ...

Multimode Phonon Lasing via Self‐Induced Optical Coherent Pumping

Laser &Photonics Reviews, EarlyView.
A silicon optomechanical nanobeam generates self‐sustained phonon lasing in multiple competing mechanical modes via self‐pulsing, an intrinsic optical modulation arising from cavity nonlinearity. This self‐organized mechanism enables robust multi‐frequency operation spanning periodic, quasi‐periodic, and chaotic regimes without external modulation. The

Wavelength dependent transmission in multimode graded-index microstructured polymer optical fibers

Frontiers in Physics
Up to now, there have been no commercial simulation tools accessible for researching the transmission properties of multimode microstructured optical fibers (MOFs). In order to avoid this problem, this study uses the time-independent power flow equation (

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.

Pinus‐derived membrane vesicles disrupt pathogenic metabolism in fungi

Plant Biology, EarlyView.
Needle‐derived vesicles from pine trees impair fungal metabolism and growth, offering a sustainable strategy to control pine pitch canker disease. Abstract Much of what we know about the biological impacts of vesicles (MVs) is derived from Arabidopsis thaliana.
