Abstract

The authors report on high-resolution photoluminescence (PL) spectroscopy and microscopy study of laterally coupled, self-assembled InAsGaAs quantum dots (QDs) by using the low-temperature near-field scanning optical microscope. In particular, they have observed characteristic doublet PL spectra, which can be indirectly but unambiguously attributed to two neighboring coupled QDs, as indicated by the identical spatial images of the PL intensity. This work may open a unique and systematic way to study the lateral coupling of single QDs for qualitative nano-optical analysis and characterization.
