Why electrical circuits operating at optical frequencies is an attractive opportunity. How a new plasmonic arrangement is used to mix electrical signals at optical frequencies. The advantages and ...

Imagine how a phone call works: Your voice is converted into electronic signals, shifted up to higher frequencies, transmitted over long distances, and then shifted back down so it can be heard ...

Scientists at the Max Planck Institute of Quantum Optics control for the first time the emission of electrons from metal tips with femtosecond lasers alone. The steering of electrons with the electric ...

Intense phase-locked terahertz (THz) pulses are the bedrock of THz lightwave electronics, where the carrier field creates a transient bias to control electrons on sub-cycle time scales. Key ...

(Nanowerk News) In the 1880s Heinrich Hertz discovered that a spark jumping between two pieces of metal emits a flash of light – rapidly oscillating electromagnetic waves – which can be picked up by ...

High-harmonic generation in solids allows probing and controlling electron dynamics in crystals on few femtosecond timescales, paving the way to lightwave electronics. In the spatial domain, recent ...
