Staschuk O. Optical fiber using photoelastic anisotropy and their application

The object - the physical processes that occur during the propagation of electromagnetic waves of optical range of the photoelastic optical fibers. Item - the properties of optical fibers in the mode of photoelastic anisotropy of the dielectric tensor elements, transient attenuation in the exchange of power between the main ordinary and extraordinary waves, polarization dispersion in anisotropic photoelastic optical fibers, electromagnetic coupling between anisotropic photoelastic optical fibers and isotropic optical fibers. Methods: Methods of the theory of transmission lines, the physics of optical communications, kristollooptiki elements of elasticity theory, methods of differential calculation of the Fourier transform apparatus. Theoretical and practical results: a method for obtaining photoelastic properties of optical fibers in the construction of optical fiber cables to compensate for the chromatic dispersion of the signal due to polarization dispersion. Obtained in the design of optical fiber optical cable with zero total dispersion of the signal due to the spiral pipe laying optical modules in the core of the cable or the use of the proposed cores profiled cables. We propose a method of equal division of the signal strength on the basis of non-reciprocal influences between the main waves in photoelastic optical fiber. Developed a method for separation of optical power, the split optical signals at wavelengths based on the electromagnetic coupling between isotropic optical fiber and optical fiber with an ordered microstructure of the rotating glass. We obtain formulas for calculating the following parameters of anisotropic photoelastic optical fibers: the elements of the dielectric constant, polarization losses, polarization dispersion, coefficient of electromagnetic coupling between isotropic optical fiber and optical fiber with an ordered microstructure of a rotating glass and pitch rotation of the microstructure of glass, at which the transfer of optical power with anisotropic optical fiber in an isotropic. Constructed simulations in which the proposed methods have been confirmed in photoelastic dispersion compensation optical fiber and separation techniques based on signal strength elektomagnitnoy between anisotropic and isotropic optical fibers.
