Optical And Mechanical Properties Of Chalcogenide Fibers

Abstract

Optical and mechanical properties of commercially available chalcogenide glasses (Asse, AsGeSe, AsGeSeTe and SbGeSe) are reported.The measured optical properties include: bulk transmittance (between 0.5 and 25 um) and the attenuation (at 10.6 um) of core and optically clad fibers. The measured mechanical properties include: bending and tensile strength testing of coated, uncoated, core and optically clad fibers.In addition to the measured physical characteristics, some potential applications of chalcogenide fibers are mentioned.

Correlation Between Thermal and Mechanical Relaxation in Chalcogenide Glass Fibers

“…Among previous works on the topic, several studies have reported on the tensile strength of chalcogenide fibers, 10–13 with typical values around 100 MPa for As 2 S 3 . The resistance to bending fracture has also been reported, 14–19 with typical values of 300 MPa for As 2 Se 3 . Both bending and tensile strength were shown to decrease with increasing fiber diameter, and sulfides appeared to have a higher strength than selenides, with tellurides being the weakest.…”

Potential of Fourier transform infrared spectroscopy and fiber optics for process control

“…The spectral range of the system is at present limited by the transmission characteristics of currently available fibers, which fall short of the information-rich fingerprint region of the mid-IR. However, continuing advances in optical fiber technology suggest that fibers with extended transmission windows and acceptably low attenuation characteristics are no longer a distant prospect (McEnroe et al, 1987); short lengths of mid-IR-transmitting chalcogenide glass fiber are already commercially available. Future developments may thus include remote spectroscopy at these longer wavelengths, particularly the fingerprint region.…”
