Au-nanoparticles strip- loaded channel waveguide

摘要

A strip-loaded channel waveguide was fabricated by deposition of Au nanoparticles (AuNPs) in a thin strip via organometallic chemical vapor deposition on top of a polystyrene slab waveguide. The beam confinement is demonstrated experimentally, despite the absence of a classical closed layer for strip loading. The AuNP density conditions for plasmonic-waveguide hybrid transmission devices are discussed.
