  • Optical fiber having high temperature insensitivity over a temperature range centered on a selected temperature and method of making same
    Patent number: 6832026
    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 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.
