In this work we investigated the emission of InAsP quantum dot molecules embedded into InP nanowires. The quantum dot molecules consist of two vertically stacked single quantum dots. This design opens unprecedented flexibility and allows for creating more interesting state configurations, compared to a single dot. Nanowire quantum dots deliver high symmetry [1] and well enhanced light extraction efficiency [2]. Furthermore, the nanowires can be grown homogeneously on predefined positions [3] with deterministic control of the quantum dot excitonic energy states [4].
