Query: Opto-Mechanical Tuning of the Polarization Properties of Micropillar
  Cavity Systems with embedded Quantum Dots   Strain tuning emerged as an appealing tool to tune fundamental optical
properties of solid state quantum emitters. In particular, the wavelength and
fine structure of quantum dot states could be tuned using hybrid
semiconductor-piezoelectric devices. Here, we show how an applied external
stress can directly impact the polarization properties of coupled InAs quantum
dot-micropillar cavity systems. In our experiment, we find that we can
reversibly tune the anisotropic polarization splitting of the fundamental
microcavity mode by approximately 60 $\mu\text{eV}$. We discuss the origin of
this tuning mechanism, which arises from an interplay between elastic
deformation and the photoelastic effect in our micropillar. Finally, we exploit
this effect to tune the quantum dot polarization opto-mechanically via the
polarization-anisotropic Purcell effect. Our work paves the way for
optomechanical and reversible tuning of the polarization and spin properties of
light-matter coupled solid state systems.
