Paper Abstract
In this work we present two experiments as evidence of negative refraction in one dimensional photonics crystals (1D
PC). Particularly the porous silicon (p-Si) multilayer structure is used as 1D PC since this structure presents periodic
dielectric components with specific refraction indexes and under certain conditions it can abnormally refract the light. In
the first experiment we show the negative refraction for two different wavelengths, one in the visible, and the other in the
infrared regions of the spectrum. In this experiment we use a fixed incidence angle for a conditioned white light beam
and we look for the emerging negative refracted beam. In the second experiment we characterize de negative refraction
observed for the same material by varying the incidence angle in a wide range. The obtained results are compared with a
theoretic prediction according a model proposed by the authors [1]. We present a brief description of the material
production and its properties, as well.
