Figure 5

Summary of various experimental proofs of gain in Si-nc. (a) Geometry used to measure the amplified spontaneous emission (ASE); (b) ASE versus the pumping length for two pumping powers; (c) ASE time decay for the various pumping conditions indicated in the inset (L is the pumping length); (d) luminescence, absorption, and gain spectra at room temperature for an Si-nc rich waveguide; (e) transmission spectra for various pumping powers (the inset shows the experimental geometry used). Data have been redrawn from [44, 45, 47].
