Optical properties of the high-index/low-index dielectric nanorod SPP cavity. (a) Electric field intensity profile of the SPP mode in the cavity. Lc = 200 nm, w = 200 nm, and d = 100 nm. (b) Cutoff frequency color map of the high-index dielectric core-silver shell SPP waveguide plotted as a function of w and d . The cutoff frequency decreases with increasing w and decreasing d. (c) Q factors at 40 K (black) and mode volumes (red) plotted as a function of the cross-sectional area, w × d. (w, d) ranges from (200 nm, 100 nm) to (60 nm, 5 nm). (d) Purcell factor plotted as a function of the cross-sectional area. Adapted from [9].
