摘要：

We have fabricated diffraction gratings by exposure of porous silicon to the focused light of UV low-power laser. Up to twenty diffraction orders could be observed with the naked eye under He-Ne laser illumination. Optical recording on porous silicon is attributed to rapid dehydrogenization of the internal surfaces of poles leading to formation of spatial structures at the external surface of porous silicon films.
