Abstract
An optical fiber for use in making components of an optical communication system has cladding and core materials the constituents of which cause a component made from the fiber to have a rate of change with respect to temperature of a response to a signal which passes through zero at a temperature T which is at or near a selected temperature, or falls within a selected temperature range; and the value of T of a fiber can be controllably changed by changing the concentration of B O in the fiber core material.
