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.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the proceedings. They include the speaker's narration with video of the slides and animations. Most include full-text papers. Interactive, searchable transcripts and closed captioning are now available for most presentations.
