Optical frequency combs are specially designed lasers that act like rulers to accurately and rapidly measure specific frequencies of light. They can be used to detect and identify chemicals and ...

Radio telescopes are instruments that capture faint radio signals from space and convert them into images of celestial bodies. To observe distant black holes clearly, multiple radio telescopes must ...

Researchers at the National Institute of Standards and Technology (NIST) have demonstrated a chip-based ...

Researchers have developed a new technology that can shape the spectrum of light emitted from a laser frequency comb across the visible and near-infrared wavelengths with more precision than ...

Optical frequency combs are coherent light sources whose spectra consist of equally spaced lines, providing a ruler in the frequency domain. Semiconductor lasers have emerged as versatile platforms ...

Device life time is a significant consideration in the cost of ownership of quantum cascade lasers (QCLs). The life time of QCLs beyond an initial burn-in period has been studied previously; however, ...
