We report on the third-order susceptibilities of the phase change material Ge2Sb2Se4Te1 in the amorphous and crystalline phase states and demonstrate enhancement of third-harmonic generation in the mid-infrared using a metasurface design.

Abstract
We report on the third-order susceptibilities of the phase change material Ge2Sb2Se4Te1 in the amorphous and crystalline phase states and demonstrate enhancement of third-harmonic generation in the mid-infrared using a metasurface design.
