Measurement of polarization mode coupling distribution in polarization maintaining fibers using microwave photonic filter technique

We propose a novel method to measure the polarization mode coupling (PMC) distribution in polarization maintaining fiber (PMF) through nondestructive way based on microwave photonic filter technique. A proof-of-concept experiment has been conducted and proves the feasibility of our proposed method. The location and strength of PMC along the PMF links can be identified precisely.
