The article focuses on the production of Germanium in the U.S. It is noted that this production comes from either the refining of imported germanium compounds or industry-generated scrap. This production series was revised downward to avoid double-counting of material imported in chemical form. A germanium refinery in Utica, New York produced germanium tetrachloride for optical fiber production. A refinery in Oklahoma produced refined germanium compounds for the production of fiber optics.

    Based on refractive index W-profile, two kinds of single-mode fibers are proposed: polarizing (bend type) and linear polarization maintaining (PM-fiber) with low losses (up to 0.35 dB/km). The polarizing W-fiber allows one to combine the dichroism in wide spectral range with opportunity to have...
