“…Frerichs in 1953 used distillation for the first time in order to improve the optical quality of vitreous As 2 S 3 . He measured a good resulting transparency for As 2 S 3 glass in the infrared and explained it [12]. It is well known that carbon, oxides and hydrogenous impurities give a high contribution to the absorption of light in the near infrared range.…”

Abstact:The aim of this paper is to present an overview of the recent achievements of our group in the fabrication and optical characterizations of As 2 S 3 microstructured optical fibers (MOFs). Firstly, we study the synthesis of high purity arsenic sulfide glasses. Then we describe the use of a versatile process using mechanical drilling for the preparation of preforms and then the drawing of MOFs including suspended core fibers. Low losses MOFs are obtained by this way, with background level of losses reaching less than 0.5 dB/m. Optical characterizations of these fibers are then reported, especially dispersion measurements. The feasibility of all-optical regeneration based on a Mamyshev regenerator is investigated, and the generation of a broadband spectrum between 1 µm and 2.6 µm by femto second pumping around 1.5 µm is presented.

“…However, experiments concerning the effects of buffer layer were mainly performed with As 2 S 3 glass, since this glass is one of the prototypical chalcogenide glasses [7]. As starting materials, arsenic (As) and sulfur (S) with purities of 99.999% were used in their elemental form to fabricate 'bulk' glass via the conventional melt-quenching route [8][9][10].…”

“…Research on the optical properties of chalcogenide glass started nearly 60 years ago [44]. Chalcogenide glasses are composed of heavy elements joined by covalent bonds, and resulted in unique optical properties making it highly suitable as a material for use in the MIR region, nonlinear optics and optical waveguides.…”

Abstract:In recent years, compound glass microsphere resonator devices have attracted increasing interest and have been widely used in sensing, microsphere lasers, and nonlinear optics. Compared with traditional silica resonators, compound glass microsphere resonators have many significant and attractive properties, such as high-Q factor, an ability to achieve high rare earth ion, wide infrared transmittance and low phonon energy. This review provides a summary and a critical assessment of the fabrication and the optical characterization of compound glasses and the related fabrication and applications of compound glass microsphere resonators.
