Tunable mid-infrared generation via wide-band four wave mixing in silicon nitride waveguides

Abijith Kowligy, Daniel Hickstein, Alex Lind +8

We experimentally demonstrate wide-band (>100 THz) frequency down-conversion of near-infrared (NIR) femtosecond-scale pulses from an Er:fiber laser to the mid-infrared (MIR) using…
