Optical technologies and optoelectronic devices are made from a variety of materials, including glasses. This is related to the optical capabilities of the glasses, which may absorb certain wavelengths and operate as optical filters, as well as be sources of radiation at various frequencies and emit coherent laser light under specified circumstances [1]. Special glasses are used in fiber optics and optoelectronics for telecommunications because they can transmit light over long distances and modify the frequency of incoming radiation [1, 2]. Tellurite-based glasses provide several advantages, including low phonon energy, a high refractive index, a high dielectric constant, superior corrosion resistance, excellent thermal and chemical stability, and a low melting point [3]. New TeO2-based glasses that mix rare earth with are particularly attractive optical amplifier materials in a broad range for wavelength division multiplexing (WDM) network systems have recently been developed [3, 4]. Rare earth oxides with unique electrical characteristics have the potential to be used as catalysts, high dielectric constant gate oxides, laser dopants, and magneto-optic memory materials [5].
