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.
