Abstract

Germanium telluride (GeTe4) chalcogenide waveguides were designed and fabricated on silicon with a ZnSe isolation layer. The thickness of the isolation layer required for negligible loss into the high refractive index silicon substrate is modelled as a function of wavelength and appropriately thick ZnSe deposited on silicon. The fabricated GeTe4 waveguides were found to guide light both in the mid- and long-wave band of the Mid-infrared wavelength spectrum.
