One-dimensional disordered photonic structures with two or more materials

Here we discuss the light transmission modulation by periodic and disordered one dimensional (1D) photonic structures. In particular, we will present some theoretical and experimental findings highlighting the peculiar optical properties of: (i) 1D periodic and disordered photonic structures made with two or more materials 1,2 ; (ii) 1D photonic structures in which the homogeneity 3 or the aggregation 4 of the high refractive index layers is controlled. We will focus also on the fabrication aspects of these structures.
