EIGENSTATES OF POLARIZATION OF ELLIPTIC SINGLE-MODE FIBERS

The degree of polarization of radiation in an elliptical polarization- maintaining fiber and the polarization states of eigenpolarization mod es of such fibers have been experimentally investigated in a wide spec tral range. It has been shown that the elliptical fibers are uniform, homogeneously twisted fibers with elliptically polarized eigenpolariza tion modes. The ellipticity of the eigenpolarization mode is independe nt of fiber length and increases with wavelength, while the azimuth of the eigenpolarization mode is spectrally independent.
