Electrical and optical properties linked to laser damage behavior in indium tin oxide

Epsilon-near-zero-materials and their unique properties are key to successful integration and miniaturization of optical components. Novel concepts, which promise significant progress in this field of research, such as optical switches and thin film electro-optical modulators, are possible, when the electrical and optical properties of ENZ-materials are carefully exploited. To achieve a greater understanding of these properties, this contribution investigates the electrical conductivity, optical transmittance as well as losses of thin indium tin oxide films and links them to their LIDT at various ultrashort pulse durations.
