Paper Abstract

Using the nanostructures supported by surface plasmon polaritons (SPPs) has been a great issue in optical sensing applications. Especially, a focused spot of SPPs, which is often called a near-field hot spot, has been numerously researched due to its high compactness beyond the diffraction limit and strong field enhancement applicable to nanoparticle sensing and tweezing. In this presentation, a novel design method for arbitrary tuning of the location of near-field hot spot controlled by the polarization of incident light is proposed. The array of nanoslit with spatially different tilted angle distribution is used for polarization-sensitive phase profile of excited SPPs.
