Simple and accurate techniques for angular alignment of a polarization-maintaining-fiber (PMF) to a linearly polarized input beam are required for many optical-fiber applications. We consider an

To achieve optimal source-to-fiber alignment in a polarization-maintaining system, the output from the PM fiber is passed through a polarizer and monitored by a power meter.
For a well-defined polarization state, it is extremely important to align the po-larization axis of the PM fibers precisely with the linear polarization axis of the source.
The choice of polarization controller instrument and corresponding optimization algorithm depends on the system and ambient conditions. In this

Polarization maintaining fiber is defined as a type of single-mode fiber that preserves the polarization state of light during propagation by introducing anisotropic stress in its core, minimizing cross
