N2 - Coherent phonon generation by picosecond optical pumpprobe spectroscopy is an important experimental tool for studying acoustic properties at the nanoscale. In this work, we integrate semiconductor micropillar cavities confining near-infrared light and 18 GHz acoustic phonons with single-mode fibers. This approach solves a major challenge of existing pump-probe experiments using mechanical delay lines: maintaining the spatiotemporal overlap of pump and probe beams on a micro-object to achieve well-controlled, reproducible mode matching conditions.
