Experimental verification of classical electromagnetically induced transparency in conductors

摘要

The effect of electromagnetically induced transparency (EIT) in non-Ohmic conductors, based on the concepts of classical nonlinear optics has been studied theoretically. We report an experimental demonstration of this effect within the mid-IR wavelength range. A low-dispersion semiconductor, i.e. ZnTe, and a highly dispersive gold film were subjected to bichromatic parametric irradiation and when specific phase matching conditions are satisfied, experimental evidence for a strong signature of EIT was found.
