Heavy metal fluoride glass fibers are approaching the stage of practical use, with potential of reaching ultra low losses in the mid IR While many research laboratories are working on lowering the optical losses, very little attention was paid to the fiber length. The goal of the program will be development of a technique to draw long length (500m) fiber with medium-low losses (<100 dB/km) and median strength of 50 kpsi or higher, from a single perform. The goal will be accomplished by increasing the perform length and increasing the perform diameter by overcladding the fluoride glass with oxide glass. The new idea, invented at Spect-Tran under Phase I of this contract, greatly improves the fiber strength, drawing properties and will improve, when fully optimized, the lifetime of the fiber. Approximately 3.25 man years level of effort will be required for successful completion of this two year program.
