Abstract
A pulsed mid-infrared pump at ë = 2173 nm is used to demonstrate wideband optical parametric gain in a low-loss 2-cm long silicon photonic wire. Using dispersion engineering to obtain negative second-order (â2) and positive fourth-order (â4) dispersion, we generate broadband modulation instability and parametric fluorescence extending from 1911 nm - 2486 nm. Using a cw probe signal to interrogate the modulation instability spectrum, we demonstrate parametric amplification > 40 dB with an on-chip gain bandwidth wider than 580 nm, as well as narrowband Raman-assisted peak gain > 50 dB.
