Visible-near-middle infrared spanning supercontinuum generation in a silicon nitride (Si3N4) waveguide

We demonstrate the generation of a supercontinuum spanning more than 1.5 octaves over the 1.2-3.7 mu m range in a silicon nitride waveguide using sub-40-fs pulses at 2.35 mu m generated by a 75 MHz Kerr-lens mode-locked Cr:ZnS laser.
