Abstract

A pulsed mid-infrared pump at λ = 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 ( β 2 ) and positive fourth-order ( β 4 ) 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 .
