The direction in which the electromagnetic field of circularly polarized light rotates can be easily reversed by applying a ...

A new plasmonic fiber probe uses linearly polarized light and energy recycling for broadband nanofocusing with resolution ...

Most laser sources produce Gaussian beams that diverge as they propagate. This natural spreading limits their effectiveness in applications that require light to remain concentrated over long ...

The inherent dispersion of laser beams limits their effectiveness in precision applications. Researchers at Chiba University, ...
