This article proposes a new type of fiber, a novel bow-tie polarization-maintaining fiber for fused-taper coupler. Based on a stress analysis of bow-tie optical fiber, a special requirements of coupling between two fibers for fused-taper coupler are presented. The optimum fiber structure has also been given. The fiber has been fabricated using MCVD. The fiber performance has also been analyzed and measured. Using this fiber, polarization-maintaining fiber coupler has been made successfully. The coupler performance: excess loss < 0.5 dB. extinction ratio > 20 dB. coupling ratio (%): 50%.
