Abstract
The increasing application of plasmonic devices causes the requirement of high-efficiency surface plasmon polariton sources. Here, we present a new surface plasmon polariton coupler based on double nanoslits. By carefully choosing the geometry parameters of the structure, the coupling efficiency can be greatly enhanced through constructive interference between the double or multislits and the input surface modulation. The good functionalities of the device such as low noise, unidirectionality and high efficiency indicate that such a structure may be a good choice as a surface plasmon polariton source for rapid development of plasmonics.
