DTIC ADA134931: High-Strength Fiber-Optic Waveguide

The objective of this program is to develop techniques
leading to an optical waveguide able to withstand a
continual strain of 2% for 10 years in a humid
environment. The approach is to use a hermetic jacket of
metal to protect the inherently strong silica fiber from
static fatigue attack by moisture. The main technical
problem is the application of a metal sheath free of
defects over multikilometer lengths without serious
degradation of the initial high strength of the pristine
silica waveguide. During the first quarter, temperature
control of the metal coating tip was identified as the
most critical parameter in eliminating sporadic openings
in the metal sheath which lead to low-strength ruptures.
Toward the end of this period we produced kilometer
lengths of metal- clad fiber substantially free of such
defects. Evaluation studies will begin next quarter. A
research study of the inherent static fatigue resistance
of silica doped with GeO2, B2O3, and P2O5 has been
initiated. Development of sample preparation and testing
techniques has been started and will continue into the
next quarter.
