Optofluidics

Surface plasmon polaritons (SPPs) may serve as ultimate data processing expedients in future nanophotonic applications. SPPs combine the high localization of electrons with the bandwidth, frequency, and propagation properties of photons, thus supplying nature with the best out of two worlds. However, although plasmonics have recently gained constantly growing scientific attention, logic devices that operate on SPPs in deep nanometer scale are yet to be demonstrated. In this chapter, we present the preliminary design, fabrication, and experimental verification of the smallest all-optical nanoplasmonic XOR logic gate.
