To conduct a full range of complex optical studies we have the broadband supercontinuum laser (FIANIUM FIU-15, NKT Photonics) coupled with tunable bandpass filters with different spectral width options (SuperK Varia and LLTF Contrast, NKT Photonics) allowing it to operate as a white light source as well as a narrow line source. The high resolution of the collected signal is provided by the spectrometer (HRS-500 or SCT320, Teledyne Prinston Instruments) coupled with a highly sensitive cooled CCD camera (PyLoN 1340x100BRX & BLAZE 400HRX, Teledyne Prinston Instruments). The samples are mounted in a closed-cycle cryostat (attoDRY800 or attoDRY1000, attocube) for temperature-dependent spectroscopic measurements. For the PL imaging, we use the home-built microscope system with white light LED (SOLIS-1D, Thorlabs) and CMOS camera (CS126CU, Thorlabs).
