  text: Spin-controlled vertical-cavity surface-emitting lasers (spin-VCSELs) offer
    a high potential to overcome several limitations of conventional purely charged-based
    laser devices. Presumably, the highest potential of spin-VCSELs lies in their
    ultrafast spin and polarization dynamics, which can be significantly faster than
    the intensity dynamics in conventional devices. Here, we experimentally demonstrate
    polarization oscillations in spin-VCSELs with frequencies up to 44 GHz. The results
    show that the oscillation frequency mainly depends on the cavity birefringence,
    which can be tuned by applying mechanical strain to the VCSEL structure. A tuning
    range of about 34 GHz is demonstrated. By measuring the polarization oscillation
    frequency and the birefringence governed mode splitting as a function of the applied
    strain simultaneously, we are able to investigate the correlation between birefringence
    and polarization oscillations in detail. The experimental findings are compared
    to numerical calculations based on the spin-flip model.
