Article Abstract
We developed a generalized field-propagating model for active optical fibers that takes into account mode beating and mode coupling through the amplifying medium. We applied the model to the particular case of a few-mode erbium doped fiber amplifier. Results from the model predict that mode coupling mediated by the amplifying medium is very low. Furthermore, we applied the model to a typical amplifier configuration. In this particular configuration, the new model predicts much lower differential modal gain than that predicted by a classical intensity model.

Nanoparticles exhibit optical and infrared sensitivity useful in optoelectronics, spectroscopy, and sensing. Capacitative and conductive coupling induces dipolar and charge transfer plasmon modes in nanoscale dimers. Optical and infrared activity of these hybridized modes are exquisitely sensitive to geometric features of the nanoscale dimer.

Colloidal gold technology has revolutionized viral diagnostics through its rapid, cost-effective, and user-friendly applications, particularly in point-of-care testing (POCT). This review synthesizes recent advancements, focusing on its role in detecting respiratory viruses, hepatitis viruses, and emerging pathogens. The technology leverages the unique optical and physicochemical properties of gold nanoparticles (AuNPs), including localized surface plasmon resonance (LSPR) and high surface-to-volume ratios, to achieve rapid antigen-antibody recognition with visual readouts within 15 min.

ConspectusMolecular photochemistry, by harnessing the excited states of organic molecules, provides a platform fundamentally distinct from thermochemistry for generating reactive open-shell or spin-active species under mild conditions. Among its diverse applications, the resurgence of the Minisci-type reaction, a transformation historically reliant on thermally initiated radical conditions, has been fueled by modern photochemical strategies with improved efficiency and selectivity. Consequently, the photochemical Minisci-type reaction ranks among the most enabling methods for C()-H functionalizations of heteroarenes, which are of particular significance in medicinal chemistry for the rapid diversification of bioactive scaffolds.
