The rainbow is not just colors—each color of light has its own frequency. The more frequencies you have, the higher the bandwidth for transmitting information.
To tame chaos in powerful semiconductor lasers, which causes instabilities, scientists have introduced another kind of chaos.
Researchers have found a method of reversibly adjusting the radiation color of nanosized light sources. Previously, radiation color could be specified only during nanoparticle synthesis, but now it can be changed after synthesis. ...
A team of researchers at Sun Yat-sen University in China has created a material with dual solar properties by adding tellurium nanoparticles to water—it showed both plasmonic-like and all-dielectric properties when exposed ...
Researchers from ITMO University developed and tested an MRI coil providing high-resolution imaging of the whole body of a mouse. Such coils are used in preclinical testing, as well as in imaging of various body systems. ...
Plasmonic waveguides open the possibility to develop dramatically miniaturized optical devices and provide a promising route towards the next generation of integrated nanophotonic circuits for information processing, optical ...
An international collaborative of researchers has demonstrated a strong light-matter interaction in suspensions and self-assembled films of tungsten disulfide nanotubes (NT-WS2). The results of the research are published ...
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 2-D material, derived ...
A team of researchers at Aalto University in Finland has found a way to use nanowires to build all-optical logic gates—a major step toward building a light-based computer. In their paper published in the journal Science ...
An international research team has found a way to make frequency conversion of light at the nanoscale 100 times more efficient. The new method is based on isolated dielectric nanoparticles supporting so-called bound states ...
