Abstract

We present the fabrication and characterisation of Dy³⁺-doped tellurite glasses and waveguides for applications in the mid-IR. The low phonon energy and large rare-earth ion solubility of tellurite glasses, as well as having infrared transmission ranges up to <5 μm, make them promising candidates for new mid-IR solid-state laser host materials. This paper presents recent achievements in the fabrication of tellurite glasses, glass characterisation and rare-earth ion spectroscopy which is compared to other glass hosts relevant to the mid-IR such as fluoride glasses. When excited with an 808 nm laser diode source, Dy³⁺ doped tellurite bulk glasses exhibited very broad fluorescence from the ⁶H_13/2 - 6H_15/2 transition which extends from 3 μm to 3.6 μm FWHM compared to 2.9 μm to 3.1 μm in Dy³⁺ doped ZBLAN glass. This broad and red-shifted fluorescence band in tellurite glass may find use in LIDAR and sensing applications as it coincides with an atmospheric transmission band, compared to the ~3 μm emission of Dy³⁺ doped ZBLAN lasers which is absorbed by atmospheric water.
