Paper Abstract

A method using all-fiber Optical Coherence Domain Polarimetry (OCDP) for polarization performance tests of PM coupler is presented in this paper. It aims to measure distributed polarization crosstalk of different devices such as coupler power coupling part, input fiber or output fiber. An all-fiber OCDP system has been built based on white light interference theory, and the detecting sensitivity of polarization crosstalk and dynamic range are better than 85 dB, meanwhile, spatial resolution reaches ±5cm. Extinction ratio, the quality of optical path connection in the 2×2 PM coupler have been measured. The results show that all-fiber OCDP has advantages to lumped extinction ratio test. This measurement provides an effective testing method for research and development of high-performance PM coupler and beam splitter.
