Phonon engineering around a single photon emitter
Final Report Abstract
The central open research question that this project addressed, was whether concepts from cavity quantum electrodynamics (CQED) can be extended to the control of the phononic emission properties of a single semiconductor quantum dot (QD). The selected experimental scheme to investigate this question were semiconductor quantum dots deterministically coupled to GaAs/AlAs micropillar cavities, which simultaneously confine both light in the near-infrared range and phonons in the range of 20GHz (80µeV). Within this project, we significantly advanced the experimental control of phonon resonators colocalizing light and sound at 20GHz. We for the first time detected clear Brillouin scattering signatures from a few-micron sized micropillar resonator. We furthermore showed coherent phonon generation and detection with record-low excitation powers in the range of 1µW, which is well compatible with micropillar resonators hosting QDs for single-photon generation. As part of the project, we implemented an experimental setup for high-resolution QD spectroscopy to evidence phonon sidebands close to the zero phonon line. The setup was optimized to allow for different excitation schemes. We designed and fabricated samples with optimized deterministic coupling between a QD and both the confined acoustic and confined optical mode of a micropillar resonator. The exploration of the externally driven regime of a single-photon source subject to an externally applied coherent phonon pulse at 20GHz is currently underway. In addition, we developed a novel class of nanophononic resonators based on the engineering of topological invariants whose acoustic confinement properties are robust to certain types of spatial disorder.
