We present an experimental signature of the Anderson localisation of microcavity polaritons, and provide a systematic study of the dependence on disorder strength. We reveal a controllable degree of localisation, as characterised by the inverse-parti

We determine experimentally the spinor interaction constants of lower polaritons ${\ensuremath{\alpha}}_{1}$ and ${\ensuremath{\alpha}}_{2}$ using a resonant pump-probe spectroscopy with a spectrally narrow pump pulse. Our experimental findings are a

A sequence of photoluminescence spectroscopy based methods are used to rigorously identify and study all the main spectral features (more than thirty emission lines) of site controlled InGaAs/AlGaAs quantum dots (QDs) grown along [111]B in inverted t

Low-temperature photoluminescence (PL) was used to optimize the structural and optical quality of 2–15 nm thick GaAs/AlGaAs quantum wells (QWs). GaAs wafers, misoriented off (1 0 0) towards 〈1 1 1〉A and 〈1 1 1〉B were used, covering the 0–
