“…The type of polarization is determined by a surface that is created by the directions of the electric intensity vector E alongside any ray in space. If this surface in space is a plane, then we speak about the linear polarization which is the simplest type of polarization, and the electric intensity vector oscillates in one direction [9], [10]. If two linearly polarized waves with the same amplitude E interfere and they have the same phase, we again obtain linearly polarized light.…”

This article is dealing with evaluation of air turbulences influence on the laser beam in the simulation box with regards to change of beam polarization state. For measurement the laser optical source LDM1550 operating at 1550 nm and polarimeter PAX5710 were used. The laser source was placed in front of simulation box that served for generation of stable turbulent environment. The simulation of turbulent environment was generated by high-speed ventilators PMD1212PMB1-A. The thermal turbulences were created by Empire CTH-5000 and Solac TH 8325 heaters. All heaters were placed along the side of simulation box. With the help of polarimeter and detector PAN5710IR3 were then subsequently recorded changes of polarization state of the optical beam with regards to changes of turbulence condition within the box. The results are then discussed and interpreted with the help of statistic methods in the end of the article.

We report a periodic thermal cycling method to investigate the dynamic response of the polarization of a laser propagating through polarization-maintaining (PM) optical fiber, driven by periodic weak temperature modulation. Consequently, temperature modulation on the surface of the coating material of the PM fiber was found to cause a continuous periodic change in the polarization state of the output laser without approaching the steady state of the resulting dynamic polarization response. Additionally, the response was found to depend on the temperature-modulation frequency and amplitude. These experimental results are qualitatively in good agreement with that of the simple theoretical model. Our research would be applied not only to the method of measuring properties of a PM optical fiber by utilizing the continuous modulation of the differential refractive index with a wide modulation-frequency range but also to various applications of the dynamic control of the periodic refractive index in materials.
