(a) Schematic of the WDR: the dielectric disk resonator made of PMMA on top of a planar Au film. (b) Topography and near-field intensity measured with a SNOM for different wavelengths in 1540–1620 nm range (, ). (c) Numerically calculated field maps ( is the main component of the electric field perpendicular to the metal surface) for the same parameters as in (b), for resonant case (1550 nm) and a non-resonant case (1575 nm). (d) WDR transmission measured at the output waveguide section (squares) compared with the numerical modeling (smooth line) for the WDR parameters in (b).

Evolution of the FSR (triangles) and modulation depth h (circles) with the disk radius at a constant gap . The crosses represent the experimental data, solid lines represent numerical results. No fitting parameters were used for numerical modeling.

FIG. 3.

Numerical results: dependence of the modulation depth (circles) and WDR resonant wavelength (diamonds) and on the separation gap at constant disk radius . The inset shows the dependence of the quality factor on the disk radius.
