Paper Abstract

Channel plasmon polaritons (CPPs) propagating along the bottom of subwavelength grooves cut into a metal surface were recently shown to exhibit strong confinement combined with low propagation loss, a feature that makes this guiding configuration very promising for the realisation of ultracompact photonic components. Here, the results of our investigations of CPP guiding by V-grooves cut into gold are presented, demonstrating efficient waveguide-ring (WR) resonator-based plasmonic components (including WR resonators and a WR resonator-based add-drop multiplexer). The CPP waveguides represent 0.5-μm-wide and 1.3-μm-deep V-grooves in gold, which are combined with 5- and 10-μm-radius ring resonators. The CPP-based components are characterized in the wavelength range of 1425-1620 nm by use of near-field optical microscopy, exhibiting the wavelength selectivity of ~40 nm.
