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].
