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. | |
