ABSTRACT:
A fiber for optical transmission, in which a core thereof for propagating light is formed of a single crystal of an ionic substance except positive ions having no closed cell electronic structure and positive ions of strong covalency. The ionic substance is a binary system compound, a ternary or more multi-system compound, or a solid solution between a binary system compound and a ternary or more multi-system compound.
