Although angle-cleaved fusion splice can greatly reduce the reflection of the fusion splicing point between photonic crystal fiber (PCF) and conventional single mode fiber, a weak residual back-reflection still exists at the fusion splicing point. A Mach-Zehnder and Michelson hybrid interferometer based on the principle of low-coherence interferometry was designed to achieve accurate positioning measurement of the residual back-reflection.Utilizing the interferometer, a -52.12 dB back reflectance of the 8° oblique splicing point between 125 μm cladding diameter solid-core PCF and conventional single mode fiber and a -49.35 dB back reflectance of the 8° oblique splicing point between 100 μm cladding diameter solid-core PCF and conventional single mode fiber were obtained.The locations of the two fusion splicing points were also acquired. The interferometer provides tools and means for precise positioning and measurement of the residual back-reflection of PCF angle-cleaved fusion splicing point, and lays a foundation for the quality improvement of the fusion splicing point.
