Summary form only given. We have presented the polarization-swapping method as a polarisation dependent loss (PDL) reducing technique for fused taper fiber couplers. The manufactured 1.48/1.55 /spl mu/m WDM fiber couplers have shown a small PDL of one tenth of that of conventional couplers. This technique is very useful to reduce the PDL of WDM fiber couplers for EDFAs in WDM fibre transmission systems.

Polarization-maintaining(PM) couplers are essential components in coherent optical communication and fiber sensor systems. The devices are required to have high performance and low-cost. Polished type PM couplers with PANDA fibers ,for example,which show low polarization crosstalk were reported so far [1].
