Abstract:

Surface plasmon-polaritons (SPPs) are TM-polarised surface waves guided by a metal-dielectric interface at optical wavelengths. Single-interface SPPs are introduced and their salient features are reviewed. Means for reducing the attenuation of SPPs are then discussed, emphasizing the long-range SPP (LRSPP) supported by the thin metal slab and the thin narrow metal stripe. Integrated optical elements based on LRSPPs in the metal stripe are then presented, including curves, Y-junction splitters, couplers, Mach-Zehnder interferometers and Bragg gratings. The application of LRSPPs to thermo-optic, electro-optic, Schottky-contact and amplifying/lasing devices, as well as to (bio)chemical sensors is briefly reviewed.
