It was a relatively quiet product announcement for Apple Computer , but then again, a speed upgrade to an existing product line is relatively unexciting. Apple unveiled three new Power Mac machines ...

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 ...

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 ...

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 ...

Somewhere between the HF projects many of us have worked on, and the visible light spectrum lies the UHF, EHF, SHF, and THF. That’s Ultra, Extremely, Super, and Tremendously High Frequency for those ...

As TR reported last December, computer industry executives have begun to question in recent years whether it’s fair, or even useful, to market new chips solely on the basis of their clock speed.

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 ...

If the chip industry is to continue boosting processor speed, it will have Chuck Gwyn to thank. Charles Gwyn--he prefers to be called Chuck and he spells Gwyn with one N, thank you--is in charge of an ...
