Optical detector The black rectangle at the centre of this image is a high-speed semiconductor photodiode that converts laser pulses to super-stable microwave frequencies. The diode is surrounded by a ...

Researchers have developed a microwave photonic chip that is capable of performing ultrafast analog electronic signal processing and computation using optics. A research team led by Professor Wang ...

Quantum physicists have found a way to make clouds of atomic-scale spins act like a single, disciplined antenna, generating microwave signals that are both powerful and remarkably long lived. Instead ...

Researchers at the National Institute of Standards and Technology (NIST) have used state-of-the-art atomic clocks, advanced light detectors, and a measurement tool called a frequency comb to boost the ...

Here’s the thing about radio signals. There is wild and interesting stuff just getting beamed around all over the place. Phrased another way, there are beautiful signals everywhere for those with ears ...

Modern-day communications rely on both fibre-optic cables and wireless radiofrequency (RF) microwave communications. Reaching higher data transmission capabilities is going to require technologies ...

How a single silicon chip was designed to be microwave and optical signal-processing engine. The various roles for which this engine can be reconfigured. The performance considerations that were ...

Using an innovative photonics topology, researchers developed an integrated microwave filter with ultra-wide dynamic range and low noise. How photonics can provide high-performance RF filtering. The ...
