Abstract

We demonstrate the fabrication of a simple metamaterial-diffraction grating device that both amplifies and converts evanescent waves into propagating ones. This is the most accessible example of such phenomena reported until now (to our knowledge), as it requires few thin film layers, operates in the visible, and can be probed with traditional optics. The metamaterial exhibits amplification of evanescent waves generated from total internal reflection. The device was fabricated over 1 cm 2 using pulsed-laser deposition and a pattern-replication technique.
