High Kerr nonlinearity hydrogenated amorphous silicon nanowires with low two photon absorption and high optical stability
arXiv:1405.2904 · doi:10.1364/OE.20.022609
Abstract
We demonstrate optically stable amorphous silicon nanowires with both high nonlinear figure of merit (FOM) of ~5 and high nonlinearity Re(γ) = 1200W-1m-1. We observe no degradation in these parameters over the entire course of our experiments including systematic study under operation at 2 W coupled peak power (i.e. ~2GW/cm2) over timescales of at least an hour.
