Webinar: Nanoscale Petahertz Electronics for Science and Technology

Dr. Donnie Keathley will be presenting at an open webinar on May 5th at 1pm EDT. The topic will be “Nanoscale Petahertz Electronics for Science and Technology.” Details for the webinar are on the registration website and below.

When matter is driven by intense, few-cycle optical field waveforms it is possible to generate free-electrons having sub-cycle, sub-femtosecond temporal structure. By driving such emission between nanoscale structures, it is possible to create compact optical-field-driven electronic devices having bandwidths approaching or even exceeding one petahertz (10^15 hertz).

In this webinar, Phillip Keathley will start by reviewing the fundamental principles behind strong-field electron emission and how it enables sub-femtosecond electron emission. From there, Dr. Keathley will review recent efforts using these properties of strong-field electron emisison for the development of chip-scale petahertz electronics. In particular, Dr. Keathley will review his team’s efforts using nanoplasmonics to enable the use of low-energy driving pulses (picojoule- to nanojoule-level) for applications such as shot-to-shot carrier-envelope-phase detection and optical field sampling with attosecond resolution. Dr. Keathley will conclude by discussing how these nanoscale devices are enabling new capabilities. These new capabilities include field-resolved optical detection as well as the ability to transfer information between devices over femtosecond timescales for petahertz-level memory and logic gates.
