Birefringence in Optical Fibers: Polarization-Maintaining Fibers and Rotation Systems

Even with a circularly symmetric design, optical fibers always show some degree of birefringence because, in reality, the symmetry is always broken by some mechanical stress or other influence. The result is a slow and uncontrollable change in the polarization of light traveling in the fiber, which is also dependent on the temperature and any bending of the fiber.

The Polarization Maintaining Fiber Rotation System principle

A polarization-maintaining fiber, which is a specialized fiber with a strong built-in birefringence rather than a fiber without birefringence, can be used to solve the aforementioned issue. Even if the fiber is bent, this polarization state will be maintained as long as the light's polarization when it is launched into it is parallel to one of the birefringent axes. Coherent mode coupling provides an understanding of the basic concept underlying this. The considerable birefringence causes the two polarization modes' propagation constants to diverge greatly, causing the relative phase of these copropagating modes to quickly drift away. Consequently, only when a disturbance along the fiber has a strong spatial Fourier component and a wavenumber that equals the difference in the propagation constants of the two polarization modes can it successfully couple both modes. The typical disturbances in the fiber fluctuate too slowly to accomplish efficient mode coupling if this difference is sufficiently big. The polarization beat length should be substantially shorter than the normal length scale that the parasitic birefringence fluctuates on, quantitatively speaking. The Polarization Maintaining Axis Rotation System is also quite necessary.

Methods for Identifying Fibers That Preserve Polarization

Adding two stress rods of a modified glass composition to preform on opposing sides of the core is a popular technique for creating strong birefringence. The stress components provide a certain amount of mechanical stress with a distinct orientation when a fiber is pulled from such a preform. Bow-tie fibers, which feature stress components with a distinct form and extend closer to the fiber core to provide a greater birefringence, can be made using numerous procedures. A further variation of that strategy is to surround the core with an ellipse cladding of various types of glass, which results in an elliptical-stress-layer fiber.

Using an elliptical core to produce so-called form birefringence is an additional method that does not rely on mechanical stress. Here, a certain amount of form birefringence is produced by the elliptical shape itself, even in the absence of any mechanical force. The Polarization Maintaining Fiber Rotation System is a vital aspect of fiber optics.
