Nanoantenna Design for Enhanced Carrier-Envelope-Phase Sensitivity

Drew Buckley, Yujia Yang, Yugu Yang-Keathley +2

Optical-field emission from nanostructured solids such as subwavelength nanoantennas can be leveraged to create sub-femtosecond, PHz-scale electronics for optical-field detection.…

Impact of DC bias on Weak Optical-Field-Driven Electron Emission in Nano-Vacuum-Gap Detectors

Marco Turchetti, Mina R. Bionta, Yujia Yang +5

In this work, we investigate multiphoton and optical-field tunneling emission from metallic surfaces with nanoscale vacuum gaps. Using time-dependent Schrodinger equation (TDSE) si…

Light Phase Detection with On-Chip Petahertz Electronic Networks

Yujia Yang, Marco Turchetti, Praful Vasireddy +6

Ultrafast light-matter interactions lead to optical-field-driven photocurrents with an attosecond-level temporal response. These photocurrents can be used to detect the carrier-env…

Antiresonance-Like Behavior in Carrier-Envelope-Phase-Sensitive Optical-Field Photoemission from Plasmonic Nanoantennas

P. D. Keathley, W. P. Putnam, P. Vasireddy +4

Given the quasi-static nature of optical-field emission and the nontrivial dependence of the emission rate on the instantaneous electric field strength, the CEP-sensitive component…

Smith-Purcell Radiation from Low-Energy Electrons

Aviram Massuda, Charles Roques-Carmes, Yujia Yang +6

Recent advances in the fabrication of nanostructures and nanoscale features in metasurfaces offer a new prospect for generating visible, light emission from low energy electrons. I…
