Highly Nonlinear Ge11.5As24Se64.5 nanowires with a nonlinear parameter up to 150,000 W−1km−1

We report the properties of dispersion-engineered nanowire waveguides fabricated in Ge11.5As24Se64.5chalcogenide glass with ? ranging from ?25,000-150,000W-1km-1. These waveguides are capable of generating broadband super-continuum when pumped with ps pulses with peak power ?20W.
