Resumo
We characterize the generation of free-carriers in a silicon strip nano-waveguide at 1550 nm performing pump-and-probe measurements. Compared with bulk silicon, we identified a higher effective two-photon absorption coefficient and a significant carrier-generation via single-photon absorption.
