This work deals with the optical characterisation of porous silicon and its application in order to obtain refractive index modulation (superlattices). In the first part, we demonstrate the homogeneity of this material on the scale of the wavelength of light studying scattering. This observation justifies the use of a mean refractive index to describe the material. Although the thickness remains well defined, velocity fluctuations appear during the electrochemical process of formation which give rise to an interface roughness. Owing this effect we had to develop a method to analyse optical measurements taking into account the scattering at the interface. Optical constants were determined using two techniques firstly by measuring the transmi...
