(a) Reflectivity spectra measured for sample HM2952 at 300 K for different values of the strip width. The period is . The spectrum in dashed line presents the transmission measured on an unprocessed sample in the multipass geometry. The inset presents a scheme of our devices, together with the relevant parameters of the grating. (b) Reflectivity minima (white dots) and simulated reflectivity (gray scale) as functions of for ; the line represents the light cone.
Reflectivity minima at 300 K (bullets), plotted as function of the cavity mode energy. The continuous line is the simulated polariton dispersion, following Eq. (1). The dashed horizontal lines are the asymptotes of the polariton branches. The star indicates the ISB absorption measured from transmission experiments at 300 K on an unprocessed sample.
Energy gap extracted from the measured dispersion of the three samples plotted as a function of the Rabi splitting at 300 K (squares) and 77 K (circles). The continuous line represents Eq. (2) with .
Relevant quantities for the three samples at 300 K (77 K).
