Free-space optical communications (FSOC), which use lasers for data transmission, are a promising approach for achieving high ...

Tailoring the light propagating from optical fibers is potentially a key aspect of multiple photonics applications, especially if the light can be shaped at the point it emerges from the fiber rather ...

- Development of the world's first practical surface-emitting laser suitable for optical fiber communications systems. - Utilization of quantum dots as an optical gain medium, enabled by NICT's ...

Laser cooling, in which carefully arranged laser beams can reduce the momentum of an atom to the point where the it can be individually caught by a magnetic field, is an important technology for ...

There are significantly different architectures for what are known as “atomic” clocks. Optically driven atomic clocks offer a new set of performance attributes. The optical atomic clocks use paired ...

Optical technology performs well but is awfully expensive. The latest in a series of breakthroughs could cure the cost problem. Photos: Lasers on a chip Michael Kanellos is editor at large at CNET ...

Engineers know that measuring dc or low-frequency electrical power is fairly straightforward, but such measurements become more difficult as you go up the spectrum into the tens-of-gigahertz range.
