Figure 4. Polariton population with off-resonant pump.

Figure 4

Transmission (a–c) and PL (d–f) spectra as cavity length is swept, traversing different longitudinal modes (q = 4, 7, 10). For PL measurements the sample is excited off-resonantly with a (λexc = 473 nm) continuous-wave laser. The lines show the dispersion of the uncoupled (white) and coupled system (colour) as in Fig. 1. (g) Polariton population as obtained from Lorentzian lineshape fits to the PL data for q = 4, 7, 10, 13 and 16. h) Maximal polariton population as a function of the Rabi splitting ħΩ. Dashed line shows a linear dependence to guide the eye.
