3D plasmonic antenna capable of focusing light into few nanometers

Adopting the proximal focused-ion-beam milling technology, researchers developed a three dimensional 4 nanometer wide gap-plasmon antenna. By squeezing the photons into a three dimensional nano space, the researchers were able to increase the intensity of light 400,000 times stronger than that of the incident light.

New polymer-piezoelectric hybrid creates potential for 'materials that compute'

Moving closer to the possibility of 'materials that compute' and wearing your computer on your sleeve, researchers have designed a responsive hybrid material that is fueled by an oscillatory chemical reaction and can perform computations based on changes in the environment or movement, and potentially even respond to human vital signs.

Interaction of tailored light with a single atom and individual nanostructures

By adapting a mode of the light field to a system under study, the interaction of light with matter can be optimized. In this context, the spatial distribution of the electric field of such a tailored mode plays an important role. Researchers use this approach to couple light to a single atom or individual nanoparticles.
