A method to accurately center quantum dots within photonic chips

Devices that capture the brilliant light from millions of quantum dots, including chip-scale lasers and optical amplifiers, have made the transition from laboratory experiments to commercial products. But newer types of quantum-dot ...

Photonics chip allows light amplification

The ability to achieve quantum-limited amplification of optical signals contained in optical fibers is arguably among the most important technological advances that are underlying our modern information society. In optical ...

Research raises hope for erbium-based integrated photonics device

An Arizona State University researcher has made another breakthrough using the rare-earth metal erbium as the gain material for an optical amplifier, this time with an achievement that will enable its use for the first time ...

Researchers get better metrics on laser potential of key material

Researchers from North Carolina State University have developed more accurate measurements of how efficiently a polymer called MEH-PPV amplifies light, which should advance efforts to develop a new generation of lasers and ...

Researchers trap light, improve laser potential of MEH-PPV polymer

(Phys.org) —Researchers from North Carolina State University have come up with a low-cost way to enhance a polymer called MEH-PPV's ability to confine light, advancing efforts to use the material to convert electricity ...

Seeing the light with nist's new noiseless optical amplifier

(Phys.org) -- Most devices that amplify light suffer from the same problem: making the image brighter also adds muddying distortion. Scientists working at the National Institute of Standards and Technology have demonstrated ...
