Polarization resolved optical spectral analysis of multimode, oxide-confined asymmetric VCSELs is presented. High-extinction-ratio polarization switching has been observed even in the multimode regime of these VCSELs. Furthermore, high-frequency polarization modulation of over a GHz with gated RF electrical modulation has been achieved.
