Abstract :
We present experimental results on surface relief gratings in GaAs and InP with high reflectivity (>85%) and polarization selectivity to normal incidence from the semiconductor side. The potential for polarization stabilization with a reduced mirror complexity for long-wavelength VCSELs is discussed.
