Paper Abstract

As we know, 2 X 2 fused taper Hi-Bi optical fiber couplers are used in many interferometric optical fiber sensor such as FOG, Michelson optical fiber interferometer and Mach-Zehnder optical fiber interferometer. In this paper, the fabrication of 3 X 3 fused taper Hi-Bi optical fiber couplers and their properties and application are discussed. The method for identifying and aligning the birefringent axes of the fibers forming coupler are described. The insertion los of couplers we fabricated is about 1.0-1.5dB. The splitting is about 1:0:1-1:1:1. The extinction ratio is about 15-20dB. We have tested some interferometer system and give some results. The wavelength of light is 1.3micrometers .
