INTERFACE FORM BIREFRINGENCE IN NATIVE OXIDED MICROCAVITIES

A novel form birefringence effect associated with periodic corrugation s in semiconductor/oxide interfaces of large-index-step high contrast Bragg mirrors of vertical microcavities is discussed in this communica tion. A simple model is proposed in which the corrugations have a squa re-wave profile with alternating refraction index whose period is much smaller than the cavity mode wavelength, This new effect has potentia l use in polarization controlled emission of vertical cavity surface e mitting lasers.
