a Transient reflectance modulation versus time for the absorber with visible probes and (b) near-infrared probes. The red and blue vertical dashed lines correspond to the device dynamics at 508 nm and 1180 nm, respectively. These are plotted in Fig. 4d as solid lines. c The absorbance of the p-polarized light in the device at an angle of 50o as calculated by the Finite Element Method, showing that light interacts strongly with individual films near their respective ENZ points. d The transient modulation response of the device at a probe wavelength of 508 nm (solid red line) and 1180 nm (solid blue line). The points are the modulation responses of the TiN film at 505 nm (red points) and the AZO film at 1210 nm (blue points). The slower TiN dynamics are shifted by 0.4 ps for clarity.
