Fig. 2: Excitation of TPP modes of Au-coated DBR (TPP cavity).

a Schematic of fabricated TPP cavity. b Calculated and measured reflection spectra at normal incidence. 2D maps of angular reflection spectra of the TPP cavity are shown in (c) to (f). For p-polarization (c) calculated and (d) measured. For s-polarization (e) calculated and (f) measured.
