Paper Abstract

Making the middle arm of parallel arranged 3x3 fiber coupler feedback, we can gain a kind of fiber coupler which couple ratio can be controlled. If a parallel arranged 3x3 fiber coupler is not completely parallel, as long as the coupling coefficient k1 between two adjacent fibers is greater than two times of the coupling coefficient k2 between two not adjacent fibers F1 and F3, couple ratio can be controlled efficiently.
