Modulation of negative index metamaterials in the near-IR range Academic Article uri icon

abstract

  • Optical modulation of the effective refractive properties of a fishnet metamaterial with a AgSiAg heterostructure is demonstrated in the near-IR range and the associated fast dynamics of negative refractive index is studied by pump-probe method. Photoexcitation of the amorphous Si layer at visible wavelength and corresponding modification of its optical parameters is found to be responsible for the observed modulation of negative refractive index in near-IR.
