Abstract

Chalcogenide glass fibers, transparent in the mid IR region, will soon find a wide range of applications, including military uses such as thermal imaging, sensing and tracking, and remote spectroscopy. We have developed chalcogenide glasses and optical fibers and bundles suitable for such military applications. Herein we describe the As₂Se₃ chalcogenide fibers and bundles with glassy core and TFE cladding, with a fiber diameter of 30-1000 μm. The optical loss, measured by CO₂ laser and FTIR spectrometer in thee temperature range of -197'C to 100'C, is less than 1 dB/m in the 3-5 μm range and less than 10 dB/m at 10.6 μm. At longer wavelengths the attenuation is much higher. The fibers maintain their transparency in the temperature range of -40*C to 70'C (military standard range).
