Radio telescopes are instruments that capture faint radio signals from space and convert them into images of celestial bodies ...

Since the conception of the laser frequency comb in the late 1990s, it has revolutionized the precise measurement of frequency and time. Beyond their initial use in optical clocks and precision ...

Researchers have shown that dissipative Kerr solitons (DKSs) can be used to create chip-based optical frequency combs with enough output power for use in optical atomic clocks and other practical ...

Since the Nobel Prize in Physics was awarded in 2005 for the invention of optical frequency combs, they have become a core technology in information systems. An optical frequency comb consists of a ...

A project at Caltech's Nonlinear Photonics Laboratory has developed a novel mode-locked laser (MLL) that could open up new applications for laser frequency combs. Published in Science, the findings ...

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 ...

There are significantly different architectures for what are known as “atomic” clocks. Optically driven atomic clocks offer a new set of performance attributes. The optical atomic clocks use paired ...

Key result A six-year-long research effort has seen researchers in Canada build a chip-scale device that can generate multiphoton entangled states. (Courtesy: Ultrafast Optical Processing Group) ...

It may seem at times that there is a divide between the optical/photonic domain and the RF one, with the terahertz zone between them as a demarcation. If you need to make a transition between the ...
