Tufts University engineers have invented a chip-sized, high-speed modulator that operates at terahertz (THz) frequencies and at room temperature at low voltages without consuming DC power. The ...

Many state-of-the-art technologies work at incredibly low temperatures. Superconducting microprocessors and quantum computers promise to revolutionize computation, but scientists need to keep them ...

Portland, Ore. Electrical engineers at the University of Texas (Austin) have demonstrated what they claim is the world's smallest silicon modulator. The device features a photonic-crystal waveguide ...

A device smaller than a grain of dust is emerging as a surprisingly powerful candidate to reshape how quantum computers are built and scaled. Instead of relying on room-filling optics and fragile lab ...

Avago Technologies has developed an optically isolated 1-bit, 2nd order Sigma-Delta (∑-∆) modulator device, the ACPL-C797T. This device converts an analog input signal into a high speed data stream ...

(Nanowerk Spotlight) The human eye's remarkable ability to detect edges—the boundaries between light and dark areas in our visual field—is a fundamental aspect of how we perceive the world. This ...
