The coupling coefficient of fused biconical taper single-mode coupler can vary from 0% to almost 100% by changing the refractive index of the surrounding media. From the data obtained the coupling mechanism cannot be attributed to power transfer between the modal fields guided by the fiber cores in the taper waist region. The results support the model of the coupling mechanism between modes guided by a glass core and an external refractive index.
