| Summary: | This paper presents the estimation of normalized
coupling power among multi coupled fibers. Power
transfer between the fibers has been determined based on
coupled mode theory using Transfer Matrix Method.
Theoretical calculation has shown that power in a fiber is
no longer to be completely transferred to other M fibers
(M>3). This is caused by the coupling coefficient
between them. The coupled power or coupling ratio
among M fibers can be controlled by maintaining the
coupling parameters. Experimentally, the change of
coupling ratio is investigated, and theoretically by
applying dc voltage to the coupling region of fiber
coupler. In three dimension, the coupling power
distribution shows that strongly depends on the coupling
coefficient and coupling length. However, by knowing
the coupling power parameters, the fiber coupler of MXN
fibers are easier to be fabricated and more applicable in
optical network system.
