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
Conventional techniques for analyzing chemical composition, such as infrared (IR) microscopy often miss critically important nanoscale details. To overcome this
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
Most manufacturing has historically been based on top-down fabrication and assembly. With rapid advances in nanotechnology, there is increasing interest in
As part of the NIST on a Chip program, the Photonic Dosimetry project is developing in-situ sub-micrometer ionizing-radiation dosimetry and calorimetry leading
