Light propagation and scattering in porous silicon nanocomposite waveguides

Résumé

We report on the first near-field observation of light propagation in a porous silicon planar waveguide. The observation has been made possible using a scattering-type scanning near field optical microscope (s-SNOM). Optical constants of the propating modes are retrieved by two methods first, from the intensity profile and then from the complex field profile, the latter being obtained with a heterodyne interferometric setup.
