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.Reserva de todos los derechosIntegrated opticsNonlinear optical materialsUltrafast opticsTEORIA DE LA SEÑAL Y COMUNICACIONESArtículo10.1364/OE.20.023838Abierto
