Acoustic control of light scattering from a single-photon emitter in the strong driving limit — •Daniel Wigger1 and Paweł Machnikowski2 — 1Fachbereich Physik, Universität Münster, Münster, Germany — 2Institute of Theoretical Physics, Wrocław University of Science and Technology, Wrocław, Poland
In the recent developments of quantum technologies, the combination of different solid state excitations into hybrid infrastructures renders a promising perspective to circumvent drawbacks of individual approaches. In this context phonons represent a versatile platform to dynamically manipulate charge carriers or spin degrees of freedom in the solid state [1]. We have recently demonstrated that in the weak optical driving limit the single-photon emission characteristics of quantum dots can be precisely controlled by surface acoustic waves (SAWs) in the spectral and the temporal domain [2]. We have also made the first steps towards acousto-optical quantum transduction [3].
In this contribution we discuss the opportunities of SAW control of spectral tuning of single emitter spectra in the strong driving limit where the spectrum is given by the Mollow triplet. We find theoretically that phonon sidebands develop which involved mixing behaviors that can exhibit crossing, anticrossing, and extinction behaviour.
