Abstract
Supercontinuum generation over 0.6 of an octave is demonstrated using a pump at 1.55µm on silicon – rich nitride waveguides. Optical characterization shows that the SRN films have a band gap of 1.85eV, and do not suffer from two photon absorption at 1.55µm. The developed waveguides have a nonlinear parameter of 550 W−1/m, 500 times larger than that in silicon nitride waveguides.
