## Abstract Planar waveguides have been achieved from oxidised porous silicon layers (OPS) which have been impregnated by solvents, Congo Red (CR) dye and poly(pβphenylene vinylene) (PPV) polymer. Optical loss has been investigated by a simple technique based on surface optical scattering measureme

## Abstract We report on the first nearβfield observation of light propagation in a porous silicon planar waveguide. The observation has been made possible using a scatteringβtype scanning near field optical microscope (sβSNOM). Optical constants of the propating modes are retrieved by two methods
