A broadband silicon mid-infrared optical parametric amplifier operating near λ=2200nm, exhibiting maximum gain >;25dB, and net off-chip gain >;13dB, is presented. Broadband cascaded four-wave-mixing spanning a 500nm spectrum is facilitated by large on-chip gain.
We show the significant impact of the longitudinal electric field component and full tensor susceptibility on the effective nonlinear parameter in subwavelength silicon nanowire waveguides. Inclusion of these effects is necessary for satisfactory wire modeling.
