Figure 1

(left) Artist’s impression of an optically pumped QD micropillar consisting of two GaAs/AlAs distributed Bragg reflectors (DBRs) and QDs on a wetting layer. (right) SEM image of an 8 μm diameter micropillar, where part of the planarizing BCB layer (visible in the background) was mechanically removed to show the layers comprising the micropillar’s DBRs. SEM, scanning electron microscopy.
