✦ Synopsis

negligible polarization effect. It is clearly seen that the degree of fusion is the dominant factor for deciding the polarization effect for the WFC, and the diameter reduction rate is a less important factor.

4. Conclusions

A vectorial EM modeling approach has been employed to investigate the coupling behaviors of the WFC with the polarization effect being included. It has been found that the degree of fusion is the dominant factor that influences the polarization effect. If the two fibers are weakly fused, the difference of the spectral coupling characteristics between the x-and y-polarizations is obvious. To design the WFC without a polarization effect, only some optimum combina-Ž . tions of the four structure parameters , ␥ , , and z are 0 allowed.
