A practical tuning mechanism for fused-tapered couplers
The axial twisting of a fused-tapered single-mode fiber coupler causes optical decoupling, which can change the power-splitting ratio of the coupler. Twisting of the coupling region causes a redistribution of the modal fields away from the coupler axis as a result of an effective refractive-index ch...
