Figure 1From: Spectral and mode properties of surface plasmon polariton waveguides studied by near-field excitation and leakage-mode radiation measurementSchematic setup of a DLSPPW excited by the NFES. The excitation light was a supercontinuum light and the incident wavelength was selected by a monochromator. The DLSPPW was made of a dielectric strip coated on a metallic thin film on a glass substrate.Back to article page
