Bringing hidden optical imperfections to light

Tiny manufacturing imperfections in optical components normally go unnoticed. Yet they can alter light in surprisingly significant ways. An international research team led by TU Darmstadt has shown that such imperfections ...

A new type of LED light could bring significant efficiency gains

Researchers at Lund University have developed a new type of light-emitting diode based on thin, branched nanowires that could offer significantly higher efficiency and lower production costs than current technology. By controlling ...

Trapped light generates nanoscale magnetization

Using an engineered metasurface that traps light, Cornell researchers have demonstrated a new way to generate strong static magnetic fields without using external magnets or magnetic materials—an approach that could advance ...

Sorry, this neutrino laser won't work, physicists say

Neutrinos are pervasive yet intangible particles that permeate the universe, streaming through whole planets, stars and our bodies by the trillions each second. The elementary particles are often described as "ghostly" for ...
