Universal power-law of terahertz optical properties of borosilicate, tellurite, and chalcogenide glass families

Terahertz (THz) time-domain spectroscopy (TDS, THz-TDS) was used to measure THz optical properties, i.e., refractive indices and absorption coefficients, of borosilicate, tellurite, and chalcogenide glass families. We observe that the THz optical properties depend on glass compositions. THz refracti...

Sumario:Terahertz (THz) time-domain spectroscopy (TDS, THz-TDS) was used to measure THz optical properties, i.e., refractive indices and absorption coefficients, of borosilicate, tellurite, and chalcogenide glass families. We observe that the THz optical properties depend on glass compositions. THz refractive indices recorded an increasing trend from borosilicate to chalcogenide and to tellurite glass families. Our results demonstrate the ability to select a glass family, system, and composition to target THz optical properties for potential use in THz optical and photonic applications. We report K and β fitting parameters for the power-law model used to describe these properties and show how it can be universally applied to several glass families.
