Igniting the air for atmospheric research

Scientists from Vienna and Moscow have created a high-energy mid-infrared laser powerful enough to create shining filaments in the air. Such devices could be used to detect chemical substances in the atmosphere.

Three-dimensional opto-electric integration

Three-dimensional (3D) integration of various materials on top of bulk silicon could be the best answer for cost-effectively marrying optical devices with electronics. A*STAR researchers have used this approach ...

Rediscovering spontaneous light emission

Berkeley Lab researchers have developed a nano-sized optical antenna that can greatly enhance the spontaneous emission of light from atoms, molecules and semiconductor quantum dots. This advance opens the ...

Engineers use disorder to control light on a nanoscale

A breakthrough by a team of researchers from UCLA, Columbia University and other institutions could lead to the more precise transfer of information in computer chips, as well as new types of optical materials ...

The first optically synchronised free-electron laser

Scientists at DESY have developed and implemented an optical synchronisation system for the soft X-ray free-electron laser FLASH, achieving facility-wide synchronisation with femtosecond precision. The performance ...
