Abstract

We fabricate and characterize a low-loss silver-based negative-index metamaterial based on the design of a recent theoretical proposal. Comparing the measured transmittance and reflectance spectra with theory reveals good agreement. We retrieve a real part of the refractive index of Re ( n ) = 2 around 1.5 μ m wavelength. The maximum of the ratio of the real to the imaginary part of the refractive index is about three at a spectral position where Re ( n ) = 1 . To the best of our knowledge, this is the best figure of merit reported for any negative-index photonic metamaterial to date.
