Fig. 2: Optical properties of the THz cavity and the perovskite.

From: Controlling the electro-optic response of a semiconducting perovskite coupled to a phonon-resonant cavity

Fig. 2

a THz TDS of the empty cavity with a gap of xgap = 1 cm; b xgap = 345 μm; c xgap = 158 μm. d Amplitude of the transmission obtained from the Fourier transform of the time trace in (a). e, f Frequency-domain transmission spectra for xgap = 345 μm and 158 μm. Blue lines show the amplitudes of the transmission; orange lines show the transmission spectrum (amplitude normalized to the spectrum for xgap = 1 cm). g Linear absorbance of methylammonium lead iodide (MAPI) perovskite outside the cavity in the THz frequency range
