Left: sketch of the working principle of the all-optical modulation of light polarization. The dielectric metasurface is illuminated by an intense laser pulse (“pump”, depicted as the purple beam), ...

A compact anisotropic laser-feedback polarimetry setup enables self-calibrating, dual-parameter birefringence measurement. The system retrieves phase retardance and fast-axis azimuth simultaneously, ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

This summary reviews recent advances in the development of nanoparticle-doped azopolymer thin films for photonic applications. By integrating nanoscale particles within a photoresponsive azopolymer ...
