Photonics-Based Oscillator Provides Precise Signals on Compact Chip
GAITHERSBURG, Md., March 15, 2024 — Many technologies — from communications, to radar and sensing, to positioning and navigation — rely on low-noise microwave signals for precise timing and synchronization. Advances in these technologies intensify the demand for stable, low-phase noise microwave sources. Although photonic lightwave systems provide advantages over conventional electronic approaches for generating low-noise microwaves, the large size and power consumption of photonic systems restrict their use to
Photonic Chip Transforms Single Light Beam into Multiple
GAITHERSBURG, Md., July 6, 2023 — Researchers at the National Institute of Standards and Technology (NIST) have devised a photonic circuit on a chip that transforms a single incoming beam of laser light into a panoply of new beams, each with a host of different optical properties....

STOCKHOLM, Oct. 9, 2012 — Separate but related quantum optics technologies — ions in a harmonic trap and photons in a cavity — that allow the measurement and control of individual quantum systems were recognized Tuesday by the Royal Swedish Academy of Sciences...
Star comb aids search for exoplanets
BOULDER, Colo. – A new laser frequency comb soon may be able to answer one of the most intriguing scientific questions: Are there other earthlike planets in our galaxy capable of supporting life as we know it? A collaboration of the National Institute of...
Star Comb Joins Quest for Other Earths
GAITHERSBURG, Md., March 8, 2012 — A new laser frequency comb soon may be able to determine whether life on other planets really exists.
Measuring the Earth from Above: 30 years (and Counting) of Hyperspectral Imaging
Jun 1, 2011 — Hyperspectral remote sensing, in which an entire spectrum is acquired at each pixel of an airborne or orbiting sensor, provides a more complete understanding of the Earth’s surface and is a tool for monitoring change. Unlike multispectral...
Packed atoms boost atomic clock performance
BOULDER, Colo. – JILA scientists have eliminated collisions between atoms in an atomic clock by packing the atoms closer together. The discovery could boost the performance of experimental atomic clocks made of thousands or tens of thousands of neutral atoms trapped...
