Construction Scheme for Dual-Core Polarization-Maintaining Fiber
In this work, we propose a polarization-maintaining, weakly coupled few-mode fiber with a uniform doping concentration, designed via a particle swarm optimization algorithm and a discrete point configuration method. The design features a circular central air hole and an. Polarization Maintaining (PM) patchcords are based on a high precision butt-style connection technique. To simultaneously optimize two inherently conflicting performance metrics, namely, birefringence and confinement loss, a multi objective genetic algorithm is. In fiber optics, polarization-maintaining optical fiber (PMF or PM fiber) is a single-mode optical fiber in which linearly polarized light, if properly launched into the fiber, maintains a linear polarization during propagation, exiting the fiber in a specific linear polarization state; there is. Thus it is important to exactly align the polarization axis of the laser source with the polarization axis of the fiber e. using the Polarization Analyzer SK010PA.
