The silicon nanophotonic wire platform can be applied toward development of integrated optical devices for the generation and processing of mid-infrared light signals. The demonstration of a mid-infrared optical parametric amplifier will be reviewed, and recent work aimed at expanded gain bandwidth and reduced pump power requirements will be presented.
We demonstrate parametric conversion with simultaneous 19.5 dB amplification, of a mid-IR 2440 nm signal to the telecom-band near 1620 nm, using silicon nanophotonic wires. Conversion over 820 nm is facilitated using higher-order waveguide dispersion.
We demonstrate an ultra-broadband optical supercontinuum extending from 1.53μm up to 2.55μm, generated in a dispersion-engineered silicon photonic wire. The supercontinuum is generated using low power mid-infrared picosecond pump pulses at 2.12μm.
We demonstrate broadband modulation instability, > 40 dB parametric amplification with on-chip gain bandwidth > 580 nm, and narrowband Raman-assisted peak on-chip gain exceeding 50 dB, using mid-infrared dispersion-engineered silicon nanophotonic wires.
Silicon nanowires have an immense potential for nonlinear optical functions. Recent work on four-wave-mixing gain in hydrogenated amorphous silicon wires at telecom wavelengths and in crystalline silicon wires in the 2μm wavelength range is reviewed.
