Abstract

We demonstrate third-harmonic generation (THG) in a dispersion-engineered slow-light photonic crystal waveguide fabricated in AMTIR-1 chalcogenide glass. Owing to the relatively low loss and low dispersion in the slow- light ( c / 30 ) regime, combined with the high nonlinear figure of merit of the material ( 2 ), we obtain a rela tively large conversion efficiency ( 1.4 × 10 8 / W 2 ), which is 30 × higher than in comparable silicon waveguides, and observe a uniform visible light pattern along the waveguide. These results widen the number of applications underpinned by THG in slow-light platforms, such as the direct observation of the spatial evolution of the propagating mode.
