講演題目: Coherent control of metamaterial functions in standing waves
Abstract
Metamaterials, artificial materials with engineered subwavelength nanostructures, can possess optical
functions unavailable for natural materials. Tuning these functions is highly desired in many applications.
Although various methods have been reported, they often have limited performance in switching speed,
energy consumption, and modulation depth. In this talk, I will present our recent results on a new control
method, coherent control, which allows for switching at THz frequency and single-photon level with
near-unity modulation. The method uses coherent light beams to create standing waves with various
electromagnetic field configurations. We have demonstrated in both theory and experiment several possible
applications including optical computation, multipole spectroscopy, and polarization-sensitive
detection.
