Si. Hosain et al., CHARACTERIZATION OF SINGLE-MODE GRADED-INDEX FIBERS - A NEW METHOD BASED ON TRANSVERSE OFFSET SPLICE LOSS, Microwave and optical technology letters, 7(7), 1994, pp. 301-304
A method of characterization has been proposed for single-mode graded-
index fibers using knowledge of the power transmission coefficient at
the splice as a function of transverse offset. The method utilizes an
analytical expression for the power transmission coefficient based on
a highly accurate variational approximation for the LP01 mode develope
d earlier. The method accurately predicts the profile shape parameter
and the normalized frequency of the fiber. (C) 1994 John Wiley & Sons,
