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. |
