  • Abstract
    A detailed study of the free carrier absorption losses at 1.5 mum has been performed on silicon-nanocrystal rib waveguides by pumping at 532 nm. At the highest photon flux, the measured losses were about 6 dB/cm. We demonstrate that the dynamics of the carrier absorption is that of the luminescence.
