A new study highlights synchronous luminescence spectroscopy as a promising way to probe plant stress and classify leaf health, adding another optical method to the toolkit for plant diagnostics.

Researchers report a lanthanide nanoparticle architecture that reconciles surface passivation with dye sensitization, delivering a dramatic near-infrared brightness gain for vascular imaging.

A new study combines optical Bloch-equation modeling with interferometric measurements to map the linear and nonlinear refractive index of warm rubidium vapor, with results that may matter for quantum photonics, precision sensing, and compact atomic devices.

A new theoretical study solves electromagnetic propagation in topological-insulator slab waveguides and finds that every supported mode becomes hybrid, with longitudinal field components, altered dispersion, and polarization rotation driven by the topological magnetoelectric response.

A new theoretical study shows that slab waveguides with a topological insulator core support exact hybrid electromagnetic modes, with longitudinal fields, altered dispersion, and polarization rotation driven by the topological magnetoelectric response.

A new theoretical study of slab waveguides with a topological-insulator core shows that every supported electromagnetic mode becomes hybridized, with longitudinal field components and polarization rotation emerging from the topological magnetoelectric response.

Researchers report an unusual strong-coupling regime in an open microcavity where an ultrathin J-aggregate film acts as an excitonic mirror, reshaping cavity boundary conditions and linking optical modes of different order.
