Figure 4. Polarization selectivity of hybrid nanomodulator.

Figure 4

(a), (b), Electromagnetic field enhancement profiles for a single hybrid nanomodulator (gap distance = 0 nm and VO2 state is metallic) for the two extreme polarization cases. (c), Collection of simulated (left and right) and experimental (middle) spectra comparing the effect of polarization and edge-to-edge separation, with blue and red curves for insulating and metallic cases, respectively. For clarity, all spectra have been normalized and the results for the perpendicular polarized light (Inline graphic) have a vertical offset of 0.2.
