Frequency conversion of mid-infrared optical signals into the telecom band using nonlinear silicon nanophotonic wires

We demonstrate parametric conversion with simultaneous 19.5dB amplification, of a mid-IR 2440nm signal to the telecom-band near 1620nm, using silicon nanophotonic wires. Conversion over 820nm is facilitated using higher-order waveguide dispersion. © 2010 Optical Society of America.
