From: Polariton condensation in an organic microcavity utilising a hybrid metal-DBR mirror
DBR–DBR control cavity condensation results. Normalised dispersions taken (a) below threshold and (b) above threshold. In both cases the red dashed line is a fit to the LPB in the linear regime. (c–e) Show the dependence of (c) PL intensity, (d) blueshift, and (e) full-width at half-maximum (FWHM) of the LPB on the absorbed pump fluence. From straight line fits to the power-dependent PL intensity in (c) (black solid lines), we determine a condensation threshold for this cavity of 180 μJ/cm2. Here we see a non-linear increase in PL intensity, a spectral blueshift, and a decrease in the FWHM of the LPB. The error bars in (d) and (e) were calculated from the error on a Gaussian fit to the LPB at each fluence.
