Simulated magnitude of Goos-Hanchen shift at λ = 568 nm wavelength as a function of the angle of incidence for light travelling from glass to air for both s- and p-polarizations.
(a) Schematic illustration of a uniform sample comprising of a thin R6G-PMMA layer spun on the top of glass substrate, (b) experimental setup used to excite all-dielectric surface waves and image the resulting leaked light, and (c) measured FP image of a R6G-PMMA(110 nm thick)/glass.
Transmission of light incident from air to glass at different incidence angles for both polarizations at 568 nm free space wavelength.
Schematic illustrations of FP images expected for (a) surface wave illumination of a uniform surface, (b) traditional illumination of a uniform surface, (c) surface wave illumination of a square lattice periodic surface, (d) traditional illumination of a square lattice periodic surface, (e) the case for super-resolution imaging using all-dielectric surface waves. In all images, the maximum collectible wavenumber kNA is denoted by a dashed ring.
FP images of periodic patterned samples with periodicity much larger than the resolving limit of each system. (a) FP image for surface wave illumination for a sample with p = 500 nm, and (b) FP image for traditional illumination of a sample with p = 380 nm.
SE images of periodic patterned samples obtained under different illumination conditions: surface wave illumination: (a) p = 240 nm and (b) p = 220 nm; traditional illumination: (c) p = 360 nm and (d) p = 320 nm.
