FIG. 1.

(a) Normalized-to-slit-width spectra of both the transmission and DWM current through a slit filled with glass. The thickness of both metal film and glass slab is 400 nm. The slit width is 400 nm. (b) Near-field intensity contourplot at the maximum of (point A on the dashed line, ), where the slit is centered at . Here and in the other figures and horizontal white light are the regions of the glass layer. Inset of (a) shows dispersion curve of the lowest TE mode of the dielectric slab .

FIG. 2.

Scattering properties of an incident waveguide mode impinging onto an array of grooves in the metal. The dielectric slab thickness is 400 nm. (b) Reflection coefficient for a single groove , as a function of groove width and for . The solid curve is for while the dashed one is for . (c) The DWM reflection , transmission , and out-of-plane scattering coefficient wavelength spectra for the Bragg mirror with . The period of the array is , the groove depth and width are 200 and 400 nm, respectively. (d) Electric field intensity spatial structure at maximum reflection [point A in (c), ]. The continuous blue curve renders the angular scattering cross-section for the wavelength of maximum [point B in (c), ]. The indentations occupy the region , with the center of the first one placed at .

Waveguide mode launcher. (b) Dependency of the efficiency coefficient upon the distance from the slit to the Bragg mirror at . The solid curve represent the exact calculation, while the dashed curve is obtained with the simplified interference model. The Bragg mirror parameters are the same as in Fig. 2, the slit width is 400 nm. (c) Electric field intensity for the point A in (b). (d) Electric field intensity for the point B in (b). The array extends to the region , with the center of the slit at .
