<p>These data are from a study involving the enhanced photon collection and imaging of a solid-state room temperature quantum light source using a near refractive index matched hemispherical solid immersion lens. We use power dependent photon counting measurements to deterministically enhance the number of photons extracted from the semi-polar Gallium Nitride host from a pre-selected quantum light source.<br></p><p>The dataset includes 13 .CSV files with the raw data for each figure in the manuscript. The filename of the files points towards each labelled subplot in each figure.</p><p><br>fig1_c.csv - 2D array of intensity data for the confocal scan map in Fig1.(c).
