Abstract
A model is presented which explains the high degree of polarization of luminescence observed in porous silicon under non resonant polarized excitation. It is assumed that the luminescence comes from Si ellipsoi ids or Si chains in SiO2. The polarization of light is obtained by a t wo-step process, selection of ellipsoids or chains elongated along the polarization direction of light and preferential emission along the s ame direction.
