The research focus on 2-D materials has intensified with its potential to modulate light for superior performance and realize applications that can enhance existing technologies. Graphene, the best known ...

Nature Physics - Knotted lines representing torus knot and figure-eight knot are produced in the polarization profile of optical beams, leading to a topological characterization of the structure of...

Nature Physics - The spin–orbit coupling of light leads to systematic wavelength-scale errors in the measurement of the position of emitters of elliptically polarized light.

Researchers at Aalto University have developed metasurfaces with extreme angle-asymmetric response. The surface reflections depend on the angle at which light hits it.

Mathematicians are devising new techniques to better predict how to tie strong knots that are useful in climbing and sailing

Over the past decades, 'storing light' has appeared as a rather controversial concept, given that a photon's inherent nature hinders its spatial confinement. The first research efforts in demonstrating ...
