In this paper a review of the reported approaches to achieve an injection Silicon laser is presented. After an initial discussion of the basic on light amplification and gain in semiconductor, we consider the limitations of silicon, in particular its band structure. Then the various approaches to get an injection silicon laser are presented and evaluated: bulk silicon, silicon nanocrystals, Er coupled silicon nanocrystals.
