Abstract

Spectral attenuation measurements were obtained on some JR transmitting waveguides to evaluate their applicability for remote sensing and laser power delivery. Since there is such a wide variety of applications for fiber optics in these areas, it is important to evaluate materials with various physical and optical properties. Three categories of waveguides where analyzed: glass, crystalline, and hollow tubes. A fluoroaluminate glass optical fiber was fabricated and the attenuation was considerably higher (102103 times higher) than the more common ZBLAN fluoride optical fibers. A Te-Se-Br glass optical fiber was evaluated and it exhibited an extended JR edge to approximately 14 rim. Attenuation measurements were conducted on single crystal sapphire, silicon, KRS-13, and KBr core/KC1 clad optical fibers. The spectral characteristics of alumina, silica glass, and mullite hollow waveguides were also determined, and all measurements were obtained using a Fourier Transform Infrared Spectrometer.
