Raman emission in porous silicon at 1.54 mu m

There have been many reports regarding visible luminescence and light emission at 1.54 mum, at room temperature, from porous silicon and from Er-doped porous silicon, respectively. Described is a different approach, based oil Raman scattering in porous silicon, to generate radiation at 1.54 mum. preliminary experimental results regarding Raman emission in porous silicon samples at 1.54 mum are also reported.
