Low TPA and free-carrier effects in silicon nanocrystal-based horizontal slot waveguides

Opt Express. 2012 Oct 8;20(21):23838-45. doi: 10.1364/OE.20.023838.

Abstract

We present the characterization of the ultrafast nonlinear dynamics of a CMOS-compatible horizontal-slot waveguide with silicon nanocrystals. Results are compared to strip silicon waveguides, and modeled with nonlinear split-step calculations. The extracted parameters show that the slot waveguide has weaker carrier effects and better nonlinear figure-of-merit than the strip waveguides.
