Abstract
An electric-arc-based scheme to generate strength-controllable weak polarization mode coupling (PMC) points in polarization maintaining fiber (PMF) is described. The resulting PMC strengths can be readily controlled to be in the very weak range of to . In this range, excellent mechanical strength combined with high return loss is achieved. An experimental quasi-distributed temperature sensor is formed by three separate PMC points in a single PMF using the electric arc method.
