Field Enhanced Optical Transmission in Metal

Abstract

This project will demonstrate how reflection and transmission of light from a metal surface can be externally controlled by few cycle laser pulses. The physical basis of the concept follows from the explanation of reflection as a classical radiation process: Light illuminating a metal surface induces current, which then radiates, and it is the interference between this radiation and the illuminating light that then accounts for the observed strong reflection and weak transmission. Thus, if it were possible to externally alter the current induced by a beam of light in a thin metal film using an additional beam, the reflection and transmission of the original beam could be modified.
