Abstract

We report on experimental observation of laser-like emission from a periodic all-silicon nanostructure formed on an electronic grade silicon-on-insulator wafer, using a highly-uniform hexagonal self-organized array of nanopores as an etch mask. Classical lasing characteristics such as threshold behavior and stimulated emission, optical gain, emission linewidth narrowing and far-field modal pattern were observed at temperatures below 70 K under optical pumping.
