Figure 2

Experimental setup. At the top left corner is a cryostat containing a sample that is pumped by a titanium:sapphire laser. The steady-state, continuous wave (cw) pumped photoluminescence is analyzed using a grating spectrometer connected to a CCD, a scanning Fabry-Pérot interferometer, a HBT setup with SPCMs and a TCSPC module. The cold mirror superimposes the pump laser onto the detection path, the pinhole provides spatial filtering, and the 850 nm longpass filter blocks scattered pump laser light. CCD, charge-coupled device; TCSPC, time-correlated single-photon counting.
