Optical properties of a silicon-nanocrystal-based-microcavity prepared by evaporation

Abstract A silicon-based microcavity constituted by a SiO/SiO 2 multilayer and Si/SiO 2 Bragg mirrors was prepared by the evaporation technique. We give details about the microcavity realization process. The optical properties of the Si nanocrystals, obtained by the thermal dissociation of the SiO layers, were analyzed by continuous-wave and angle-resolved photoluminescence (PL) experiments. The results show a strong anisotropy of the light emitted by the silicon nanocrystals for a cavity constituted by mirrors with only two distributed Bragg reflectors (DBR).
