Abstract

A hybrid device comprising a (Al)GaAs quantum dot heterostructure and a LiNbO{\$}{\_}3{\$} surface acoustic wave resonator is fabricated by heterointegration. High acoustic quality factors {\$}Q{\textgreater}4000{\$} are demonstrated for an operation frequency {\$}f\backslashapprox 300{\$} MHz. Frequency and position dependent optomechanical coupling of single quantum dots and the resonator modes is observed. Finally, fingerprints of cavity-mediated non-linear optomechanical coupling are detected for high acoustic pump levels.
