Pavesi %J Advances in Optical Technologies %D 2008 %I Hindawi Publishing Corporation %R 10.1155/2008/416926 %X Silicon the material per excellence for electronics is not used for sourcing light due to the lack of efficient light emitters and lasers. In this review, after having introduced the basics on lasing, I will discuss the physical reasons why silicon is not a laser material and the approaches to make it lasing. I will start with bulk silicon, then I will discuss silicon nanocrystals and Er3 %U http://www.hindawi.com/journals/aot/2008/416926/
