Plasmonic lenses can be made extremely small to enable integration into focal-plane array detectors for full Stokes-parameter polarimetric imaging.

A new type of liquid-crystal device has been fabricated to generate a tunable, graded refractive index across the depth of each pixel.

The exceptional flexibility and diversity of artificial media make it possible to adjust their properties on the fly, with potential practical use in areas such as sensing and switching.

Laue scattering of visible light with an internal refractive-index contrast of less than 1% shows that kinematic-scattering theory is applicable.

Single atoms mediate interactions between modes of light, making optical quantum computing possible even without using single photons or nonlinear optics.
