Engineers build smallest integrated Kerr frequency comb generator

Optical frequency combs can enable ultrafast processes in physics, biology, and chemistry, as well as improve communication and navigation, medical testing, and security. The Nobel Prize in Physics 2005 was awarded to the ...

New IR instrument searches for habitable planets

A new instrument to search for potentially habitable/inhabited planets has started operation at the Subaru Telescope. This instrument, IRD (InfraRed Doppler), will look for habitable planets around red dwarf stars. Astronomers ...

A laser that tracks like a hound

University of Adelaide researchers have created a laser that can "smell" different gases within a sample.

Combing light for tell-tale chemical fingerprints

A laser-based technique that can scan and lock on to molecular vibrational signals that are normally too complex to resolve clearly could enable production of sensors for multi-species identification in harsh environments, ...

Laser frequency combs may be the future of Wi-Fi

Wi-Fi and cellular data traffic are increasing exponentially but, unless the capacity of wireless links can be increased, all that traffic is bound to lead to unacceptable bottlenecks.

Team shows tiny frequency combs are reliable measurement tools

In an advance that could shrink many measurement technologies, scientists at the National Institute of Standards and Technology (NIST) and partners have demonstrated the first miniaturized devices that can generate desired ...
