Development of a variable fiber optic coupler

The tuning of the coupling ratio of fused fiber optic couplers over a wide range is demonstrated. The variable coupling ratio is achieved by applying a deflection to the fused biconical taper coupler. The dependency of the variable coupler on the deflection is elaborated. It is found that in the ran...

Summary:The tuning of the coupling ratio of fused fiber optic couplers over a wide range is demonstrated. The variable coupling ratio is achieved by applying a deflection to the fused biconical taper coupler. The dependency of the variable coupler on the deflection is elaborated. It is found that in the range of 0.8 mm deflection, the coupling ratio can be varied from 11% to 92% with the excess loss less than 0.1 dB.
