Paper Abstract

We have conducted an extensive experimental investigations of optical properties of porous silicon with special emphasis to their dependence upon the microstructure of the material. We present the results of direct STM observation of `quantum wires' in porous silicon and time- resolved optical spectrum of nonlinear transmittance, featuring sharp peaks which can be attributed to the saturation of the optical transition between spatially quantized levels of carriers in `quantum wires'. It was found that porous silicon is strongly nonlinear optical material with Im(chi) (3) approximately equals 10-8 esu.
