KAIST researchers tested optical frequency comb lasers as reference signals for radio astronomy, aiming to synchronize radio telescopes with light-based timing in VLBI observations.

Optical cavities form the cornerstone of high-precision laser frequency stabilisation by confining light between mirrors to produce well-defined resonant modes. In these systems, the stability of the ...

Very-long baseline interferometry (VLBI) is a technique in radio astronomy whereby multiple radio telescopes cooperate to ...

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 ...

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 ...

A tunable metasurface can control optical light in space and time, offering a path toward new ways of wirelessly and securely transmitting large amounts of data both on Earth and in space. It is a ...

Chinese scientists have pushed solid-state vacuum ultraviolet laser technology to a new milestone by ...
