Abstract

Microscopy provides a suitable technique for local probing of small ensembles of (or even individual) QD's, and when combined with the detection of second-harmonic (SH) generation the technique becomes suitable to reveal tiny changes of symmetry originating either in the material structures or in the illumination itself. Thus, a combination of scanning microscopy with SH detection may be a highly suitable candidate to reveal the presence of QD's embedded in an otherwise isotropic material. We have used scanning far-field (SFOM) and scanning near field optical microscopy (SNOM) techniques to locally probe small ensembles of self-assembled InAlGaAs QD's.
