We fabricate and investigate wavelength selective components utilizing channel plasmon polaritons (CPPs) and operate at telecom wavelengths: a waveguide-ring resonator-based add-drop multiplexer (WRR-ADM) and a compact (3.75-mu m-long) Bragg grating filter (BGF). The CPP waveguides represent 0.5-mu m-wide and 1.3-mu m-deep V-grooves in gold, which are combined with a 5-mu m-radius ring resonator (in the WRR-ADM) or 0.5-mu m-long wells milled with the period of 0.75 mu m across a groove (in the BGF). The CPP-based components are characterized in the wavelength range of 1425-1600 nm by use of near-field optical microscopy, exhibiting the wavelength selectivity of similar to 40 nm.
