Figure 3
The optical properties of the SPP modes with m = 1, 2, and 3. (a) The resonant wavelengths and mode volumes are plotted as a function of L. An extremely small mode volume on the order of 10-5 μm3 results. (b) The Q factors and confinement factors are plotted as a function of L at low temperature (20 K). (c) The Q factor of the SPP mode of m = 1 for the cavity with L = 40 nm is plotted as a function of temperature. Adapted from [2].
