Supercontinuum generation in 800nm thick ultra-low loss silicon nitride waveguides

Résumé

We report SCG over 1.4 octave(from 620nm to 1.5µm) by pumping at 1060nm on a dispersion-engineered ultra low-loss SiN integrated waveguide with femtosecond pulse of 300W as peak power. We demonstrate SCG over 2.5 octaves(from 580nm to 2.05µm) when a wider and longer waveguide being pumped at 1550nm with peak power of 800W. We also experimentally observe a 4.5 octaves(from 500nm to 2.75µm) SCG by pumping at 1550nm on the 800nm thick SiN platform. We show the versatility of CEA LETI 800nm thick ultra-low loss SiN platform to SCG,
