Structural phase change functionality in photonic metamaterials
Structural phase change functionality in photonic metamaterials
We report here on recent advances in the development of versatile, planar photonic metamaterial solutions to provide a new generation of nanoscale optical switching and memory devices:
Optically-induced phase transitions in germanium antimony telluride (GST) - a member of the chalcogenide alloy family upon which re-writable optical disc and phase-change RAM technologies are based – provide for the engineering of non-volatile metamaterial transmission/reflection modulators for the near- to mid-infrared range with thicknesses down to 1/27 of the operating wavelength;
Dielectric optomechanical metamaterials, wherein optical forces drive spatial rearrangements of the structural elements, offer a new paradigm (which is inherently free of Joule losses) for achieving strong optical nonlinearity, optical bistability and asymmetric transmission at intensity levels of only a few hundred µW/µm2.

Abstract
We report here on recent advances in the development of versatile, planar photonic metamaterial solutions to provide a new generation of nanoscale optical switching and memory devices:
Optically-induced phase transitions in germanium antimony telluride (GST) - a member of the chalcogenide alloy family upon which re-writable optical disc and phase-change RAM technologies are based – provide for the engineering of non-volatile metamaterial transmission/reflection modulators for the near- to mid-infrared range with thicknesses down to 1/27 of the operating wavelength;
Dielectric optomechanical metamaterials, wherein optical forces drive spatial rearrangements of the structural elements, offer a new paradigm (which is inherently free of Joule losses) for achieving strong optical nonlinearity, optical bistability and asymmetric transmission at intensity levels of only a few hundred µW/µm2.
