Phase-change and optomechanical functionalities in photonic metamaterials
Phase-change and optomechanical functionalities in photonic metamaterials
Switchable and nonlinear metamaterials, with properties surpassing those of natural media, will underpin the next stage of the photonic technological revolution, providing a functional platform for nanoscale ‘meta-devices’. 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:
We demonstrate that 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.
And we introduce all-dielectric optomechanical metamaterials, wherein optical forces drive changes in structural configuration, as a new paradigm (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
Switchable and nonlinear metamaterials, with properties surpassing those of natural media, will underpin the next stage of the photonic technological revolution, providing a functional platform for nanoscale ‘meta-devices’. 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:
We demonstrate that 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.
And we introduce all-dielectric optomechanical metamaterials, wherein optical forces drive changes in structural configuration, as a new paradigm (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.
