dc.description.abstract | Within this work we propose and demonstrate a technological approach to efficiently suppress excitation laser stray-light in resonance fluorescence experiments on quantum dot-micropillars. To ensure efficient stray-light suppression, their fabrication process includes a planarization step and the subsequent covering with a titanium mask to fabricate self-aligned apertures at the micropillar positions. These apertures aim at limiting laser straylight in side-excitation vertical-detection configuration, while enabling detection of the optical signal through the top facet of the micropillars. Beneficial effects of these apertures are proven and quantitatively evaluated within a statistical study in which we determine and compare the stray-light suppression of 48 micropillars with and without metal apertures. Actual resonance fluorescence experiments on single quantum dots coupled to the cavity mode prove the relevance of the proposed approach and demonstrate that it will foster further studies on cavity quantum electrodynamics phenomena under coherent optical excitation. | |
