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…

Examining the Transition from Multiphoton to Optical-Field Photoemission From Silicon Nanostructures
Phillip D. Keathley, William P. Putnam, Guillaume Laurent +2
We perform a detailed experimental and theoretical study of the transition from multiphoton to optical-field photoemission from n-doped, single-crystal silicon nanotips. Around thi…
