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.
