New type of low-energy nanolaser that shines in all directions

Researchers in Eindhoven have developed a new type of low-energy, nanoscale laser that shines in all directions. The key to its omnidirectional light emission is the introduction of something that is usually highly undesirable ...

Controlling electrons in time and space

In an electron microscope, electrons are emitted by pointy metal tips, so they can be steered and controlled with high precision. Recently, such metal tips have also been used as high precision electron sources for generating ...

A little impurity makes nanolasers shine

Scientists at ANU (The Australian National University) have improved the performance of tiny lasers by adding impurities, in a discovery which will be central to the development of low-cost biomedical sensors, quantum computing, ...

Researchers transform slow emitters into fast light sources

Researchers from Brown University, in collaboration with colleagues from Harvard, have developed a new way to control light from phosphorescent emitters at very high speeds. The technique provides a new approach to modulation ...

Photonic crystal nanolaser biosensor simplifies DNA detection

A simple method to sense DNA, as well as potential biomarker proteins of cancer or other diseases such as Alzheimer's, may soon be within reach - thanks to the work of a team of Yokohama National University researchers in ...
