    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.

    Abstract: An infrared optical fiber containing 30 to 70 % by weight of silver chloride and silver bromide and having a diameter of not more than 0.35 mm has a high mechanical strength. Accordingly, even when this fiber is bent ten thousand times repeatedly at a curvature of 20 mm in radius, which constitutes the condition required of the infrared optical fiber when it is used in a human body, a decrease of the laser beam transmitting capacity thereof, which causes the infrared optical fiber to be burnt, does not occur. This fiber has excellent optical characteristics with respect to an outgoing beam. When a proper load is imposed on this fiber, a non-curved, i.e. linear infrared optical fiber having excellent optical characteristics with respect to an outgoing beam can be obtained. This enables an infrared optical fiber to be manufactured stably in a shorter period of time.
