Selected Pictures

Fig. 1: (a) Illustration of a QD-micropillar nanolaser. The performance is determined by the interplay of electrical and optical design parameters. (b) Characteristics of a nanolaser exploiting cQED effects. The transition to lasing is quantified by the 2nd order correlation function g(2)(0).
