Petahertz Optical Switches and Transistors

Case ID:

This technology is a system and method configured for measurement of an electronic delay response of a dielectric system triggered by a strong driving optical field of few-cycle attosecond pulses. The produced electronic response is used to demonstrate all-optical light field sampling metrological tool operating with attosecond resolution. On-demand quantum electron motion control in solid-state with the use of synthesized waveforms is demonstrated to realize ultrafast optical switches and petahertz electronics.

Attosecond pulses generation and spectroscopic measurements in gases and solids open a new window into the study of electronic driven by strong fields in real-time. Understanding electron dynamics and the related phase transition will allow for further study into quicker processing, ultrafast dynamics, and ultrafast systems.
