Optical fiber having high temperature insensitivity over a temperature range centered on a selected temperature and method of making same

摘要

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 Tm which is at or near a selected temperature, or falls within a selected temperature range; and the value of Tm of a fiber can be controllably changed by changing the concentration of B2O3 in the fiber core material.
