Direct imaging of localized surface plasmon polaritons: Sinan Balci, Ertugrul Karademir, Coskun Kocabas, Atilla Aydinli
In this Letter, we report on dark field imaging of localized surface plasmon polaritons (SPPs) in plasmonic waveguiding bands formed by plasmonic coupled cavities. We image the light scattered from SPPs in the plasmonic cavities excited by a tunable light source. Tuning the excitation wavelength, ... [Opt. Lett. 36, 3401-3403 (2011)]
