Polarization-maintaining fused taper fiber couplers using twin-peak core fibers

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].
