Microcombs – chip-scale devices that generate and measure frequencies of light with exquisite accuracy – have transformed timekeeping and boosted optical
Frequency combs — specialized lasers that act like rulers to measure light — are now being brought down to a low-power, chip-scale form. NIST researchers David
Devices that capture the brilliant light from millions of quantum dots, including chip-scale lasers and optical amplifiers, have made the transition from
Chip-based devices known as frequency combs, which measure the frequency of light waves with unparalleled precision, have revolutionized time keeping, the
In research, sometimes the bumpy path proves to be the best one. By creating tiny, periodic bumps in a miniature racetrack for light, researchers at the
Researchers at NIST and their colleagues have built a superconducting camera containing 400,000 pixels — 400 times more than any other device of its type.
The creation and detection of single photons (the smallest units of light) has grown in a few decades from an experimental laboratory pursuit to an important
Max Planck, one of the Twentieth Century’s most eminent physicists, observed, "An experiment is a question that science poses to Nature, and a measurement is
Physicist Jun Ye has a knack for making every second count—literally. At JILA, a joint research institute of the University of Colorado and the National
David Gerrold, a prolific American author, and screenwriter, summarizes the progress of the last 120 years when he observes, “In the 20th century, we had a
Researchers at the National Institute of Standards and Technology (NIST) have developed chip-scale devices for simultaneously manipulating the color, focus
In the Lilliputian world of nanofabrication, where billions of microscopic circuit elements are sculpted or imprinted on a fingernail-sized silicon chip
In two new studies, researchers at the National Institute of Standards and Technology (NIST) have greatly improved the efficiency and power output of a series
The ability to transmit and manipulate the smallest unit of light, the photon, with minimal loss, plays a pivotal role in optical communications as well as
For decades, astronomers and physicists have been trying to solve one of the deepest mysteries about the cosmos: An estimated 85% of its mass is missing.
New technologies are always invented in the labs at NIST every year. The researchers dedicate their time to discovering these new solutions to problems and
Cutting intricate patterns as small as several billionths of a meter deep and wide, the focused ion beam (FIB) is an essential tool for deconstructing and
Shine a flashlight into murky pond water and the beam won’t penetrate very far. Absorption and scattering rapidly diminishes the intensity of the light beam
Five hundred million years ago, the oceans teemed with trillions of trilobites — creatures that were distant cousins of horseshoe crabs. All trilobites had a
Like a vocal coach who extends the octave range of an opera singer, researchers at the National Institute of Standards and Technology (NIST) have expanded by
Researchers at the National Institute of Standards and Technology (NIST) and their colleagues have significantly improved the ability of a type of optical
Just as a meter stick with hundreds of tick marks can be used to measure distances with great precision, a device known as a laser frequency comb, with its
Researchers at the National Institute of Standards and Technology (NIST) and their colleagues have developed an optical switch that routes light from one
Imagine being able to shape a pulse of light in any conceivable manner—compressing it, stretching it, splitting it in two, changing its intensity or altering
