Abstract:

This report summarizes results obtained under Phase I SBIR program aimed at developing new techniques for fabricating long lengths of heavy metal fluoride glass HMFG optical fiber. A new method for overcladding conventional HMFG performs with a low melting oxide glass was developed, and improvements in the rotational casting method were made to increase preform length. The resulting composite glass canes consist of a fluoride glass overcoat layer to enhance strength and chemical durability. To show feasibility, prototype optical fiber preforms up to 1.6 cm in diameter with lengths of 22 cm were fabricated. These were drawn into optical fibers with lengths up to 900 meters.
