Abstract: An in-depth analysis of the phase noise of a microwave oscillator based on dual-wavelength stimulated Brillouin scattering is presented. The system is investigated under the influence of ...

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 ...

Geiger-mode avalanche photodiodes (GM-APDs) are highly sensitive light detectors, capable of detecting single photons.

Richard Fishacre challenged the scientific orthodoxy of his day, and contemporary astrophysics has vindicated his position.

During the 1240s, Richard Fishacre, a Dominican friar at Oxford University, used his knowledge of light and color to show ...

A special technique produces very wide loop BWs in high-frequency PLLs (and hence, indirect (PLL) synthesizers), thereby achieving very low phase noise rivaling that of direct (MMD) synthesizers. A ...

The James Webb Space Telescope has proven itself capable of seeing 98% of the way back to the Big Bang,” said Peter Jakobsen, affiliate professor of astrophysics at the University of Copenhagen ...
