Recent advances in the technology of fabricating infrared optical-fiber waveguides together with advances in the development of highly transparent infrared window materials show great promise for the development of ultra low-loss infrared transmitting fiber-optical waveguides suitable for communication links. Theoretical calculations indicate the feasibility of using polycrystalline alkali halides as waveguides with predicted losses as low as 0.01 dB/km at selected near-infrared wavelengths.
