‘Exceptional’ Research: Unexpected Light Behavior May Be Harnessed to Improve Optical Communications and Sensors

April 21, 2022

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

Inspired by Prehistoric Creatures, NIST Researchers Make Record-Setting Lenses

April 19, 2022

Five hundred million years ago, the oceans teemed with trillions of trilobites — creatures that were distant cousins of horseshoe crabs. All trilobites had a

Scientists Greatly Expand the Frequencies Generated by a Miniature Optical Ruler

February 23, 2022

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

PTIR combines the spatial resolution of AFM with the specificity of absorption spectroscopy

Nano-Chemical Imaging and -Spectroscopy (IR, nIR, VIS)

Ongoing

Conventional techniques for analyzing chemical composition, such as infrared (IR) microscopy often miss critically important nanoscale details. To overcome this

Frequency Conversion Interfaces for Photonic Quantum Systems

Ongoing

Optical frequency conversion, in which the color of light is changed, is a process that has numerous applications in physics and technology. For example, green

Modeling and Simulation of Nanofabrication (Archived)
