Abstract

Fiber optical waveguides have been fabricated which have the unique capability of transmitting the long wavelength radiation required in certain sensor, long distance communication, and power delivery systems. These polycrystalline fibers, made from alkali and thallium halides, were prepared using hot extrusion techniques. The fiber losses, however, are much greater than the projected losses for the crystalline fiber materials. To determine the source of our IR fiber losses, we have measured the attenuation due to scattering and absorption between 4 and 10 µm in KRS-5 (TIBrl) fibers.
