Light has bidirectional transmission reciprocity in common dielectric material. Breaking this reciprocity in the directi…

For the first time, researchers from UNIGE and MBI in Berlin have placed an electron in a dual state -- neither freed nor bound -- thus confirming a hypothesis from the 1970s

The more intense a laser is, the easier should it be to ionise the atom--in other words, to tear the electrons away from…

Engineers team up to reduce the size, cost and power requirements of an optical frequency device

Optical frequency synthesizers provide unprecedented performance but until now have been large, expensive and power hung…

By placing the most magnetic element of the periodic table into a quantum version of a popular desktop toy, Stanford scientists explore the emergence of quantum chaos and thermal equilibrium.

Lev and his group built their own quantum version of Newton’s cradle in order to answer questions about how the chaotic…

Metal-free metamaterial can be swiftly tuned to create changing electromagnetic effects

For this study, the cylinders were sized to interact with terahertz waves—a band of the electromagnetic spectrum that si…

Rice University scientists make tunable light-matter couplings in nanotube films

In the new work, Kono and Rice postdoctoral researcher and lead author Weilu Gao combined techniques from the earlier pa…

A research group from ITMO University has developed the first-ever controlled nanodiamond-based light source. Experiment…

Artificial optical materials could allow cheaper, flatter, more efficient detectors for night vision and other uses.

The new approach uses a flat, artificial material composed of nanostructured optical elements, instead of the usual thic…

New additive manufacturing technique could be used to combine optics, microfluidics and electronics on a single chip

Researchers have developed an inkjet printing technique that can be used to print optical components such as waveguides

The elusive quantum mechanical phenomenon of entanglement has now been made a reality in objects almost macroscopic in size
