Abstract

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.

Abstract

We report the properties of a Ge11.5As24Se64.5chalcogenide glass and demonstrate that dispersion-engineered rib waveguides can be fabricated in this material with nonlinear parameters >30,000W-1km-1: the highest value yet reported for a glass planar waveguide.
