A Hybrid (Al)GaAs-LiNbO${}_3$ Surface Acoustic Wave Resonator for Cavity Quantum Dot Optomechanics

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 $Q>4000$ are demonstrated for an operation frequency $f\approx 300$ MHz. The measured large quality factor-frequency products $Q\times f>10^{12}$ ensures the suppression of decoherence due to thermal noise for temperatures exceeding $T>50\mathrm{K}$. Frequency and position dependent optomechanical coupling of single quantum dots and the resonator modes is observed.
