(color online) FOV of NWRIM. (a) Simulated cross-sectional field distribution with fluorescent CdS nanowire on Al₂O₃–SiO₂–Si double layer substrate. Intensity is shown on a log scale. (b) Simulated field magnitude in Al₂O₃ film along propagation direction. (c) CNR of images of fabricated slot structures at different distances from fluorescent CdS nanowire light source, achieved with film waveguide fabricated at 300 °C and room temperature, respectively. Inset shows two-dimensional “ZJU” pattern illuminated by NWR. The area circled by NWR is . Reproduced with permission from Refs. [50] and [51].
