Spatially Asymmetric Hot-Carrier Transport for Ultrafast Generation of Electromagnetic Waves

Mohammad Taghinejad, Kyutae Lee, Andrew S. Kim, Mark L. Brongersma, and Wenshan Cai

Not Accessible

Your library or personal account may give you access

Abstract

We demonstrate the ultrafast conversion of statically passive dielectrics (e.g., amorphous TiO2) to transient second-order nonlinear media following the femtosecond transfer of hot electrons, enabling active control of nonlinear interactions, envisioned for terahertz functionalities.
