TABLE I. Investigated samples, active layers, microdisk geometries, and microlaser characteristics.
Table I presents the pumping threshold for each sam- sam-ple. We can observe a clear difference between the two families of QWs: the threshold is one order of magnitude smaller for InGaN/GaN QW microdisks (3 mJ .cm 2 per pulse) than for GaN/AlN QW microdis
