The ability to precisely control and change properties of a photon, including polarization, position in space, and arrival time, gave rise to a wide range of communication technologies we use today, ...

Nanomechanical resonators are miniature vibrating structures on chips that oscillate at frequencies ranging from a few ...

Lithium niobate (LN) powers a newly developed optical metasurface for shaping and guiding light waves. Leveraging the electro-optical effect of lithium niobate, the device applies different electric ...

One of the most frequently touted measures of processor performance is a given chip's speed in gigahertz. Processors with higher GHz ratings can, theoretically, do more in a given unit of time than ...

Researchers in the US and Italy have made the first integrated graphene digital circuits that function at gigahertz frequencies. The circuits are ring oscillators and the work could be an important ...

OFC 2026 -- Mixed-Signal Devices, a leader in multi-gigahertz timing solutions, today announced it will showcase its latest digitally synthesized timing technologies delivering 20 femtosecond jitter ...

The ability to probe quantum systems on short timescales is central to the advancement of quantum technology. Here we show that this is possible using an off-resonant dispersive probe. By applying a ...

A silicon-lithium niobate metasurface controls light through air at gigahertz speeds, advancing compact systems for optical communication and signal routing. (Nanowerk Spotlight) Optical systems that ...
