Resumé

Dielectric-loaded plasmonic waveguide-racetrack resonators (WRTRs) were designed and fabricated for operating at near-infrared wavelengths (750–850 nm) and characterized using leakage-radiation microscopy. The transmission spectra of the WRTRs are found experimentally and compared to the calculated analytical expression. The wavelength-dependent parameters of the analytical expression, i.e. the propagation length and effective-index dispersion, were also estimated experimentally by leakage-radiation imaging of direct and Fourier space, respectively. The fabricated structures exhibited high extinction ratio (~20 dB) and good agreement between calculated and measured transmission values.
