Russian physicists study laser beam compressed into thin filament

A group of Russian scientists recently presented their research into the process of laser pulse filamentation—the effect produced when a laser beam propagating in air focuses into a filament. The researchers discovered ...

Putting a new spin on plasmonics

Researchers at Finland's Aalto University have discovered a novel way of combining plasmonic and magneto-optical effects. They experimentally demonstrated that patterning of magnetic materials into arrays of nanoscale dots ...

Throwing light on a mysterious human 'superpower'

Most people, at some point in their lives, have dreamt of being able to fly like Superman or develop superhuman strength like the Hulk. But very few know that we human beings have a "superpower" of our own, which almost anybody ...

Plasmon-enhanced Polarization-selective filter

As we all know, some optical devices can only work with a certain incident polarization direction. In this case, a polarizer is necessary to shift the polarization direction of linearly polarized light. A common polarizer ...

Team uses carbon nanotubes for polarized-light detection

Using carpets of aligned carbon nanotubes, researchers from Rice University and Sandia National Laboratories have created a solid-state electronic device that is hardwired to detect polarized light across a broad swath of ...

Researchers develop light transistor

TU Vienna has managed to turn the oscillation direction of beams of light – simply by applying an electrical current to a special material. This way, a transistor can be built that functions with light instead of electrical ...
