The phase-change technology behind rewritable optical disks and the latest generation of electronic memories can also offer high contrast plasmonic switching functionality. Numerical simulations illustrate the extent of this potential while preliminary experiments show that a silver/gallium-lanthanum-sulphide interface can support surface plasmon-polaritons and demonstrate the principle of plasmonic modulation through reversible photo-induced changes in the chalcogenide. (© 2010 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)The functional materials behind rewritable optical disk and emergent solid state memory technologies offer a new switching paradigm for photo- and electro-activated plasmonic signal modulation in future highly-integrated nanophotonic devices. In their Letter the authors explore details of these possibilities on the basis of numerical modelling, and they report on the advent of experimental realisation by showing that the interface between silver and gallium lanthanum sulphide can support surface plasmon-polaritons. © 2010 WILEY-VCH Verlag GmbH & Co.
