Bell-shaped refractive index profiles of multimode optical fibers and methods for calculating their optical properties

V. M. Gololobov, V. S. Motolygin, V. Zemlyakov, J. Gao Russian Research Institute, LLC Huawei Tech Company, Russia, Moscow Abstract: The paper investigates the optical properties of multimode fibres whose profiles are represented by a broad class of bell-shaped analytical functions. We consider the profiles with different curvature and described by (i) the Fermi–Dirac distribution… Read More »

Coherent resonances in a dipole-broadened profile of selective reflection from the transparent dielectric–atomic rubidium vapour interface

V. A. Sautenkov, S. A. Saakyan, A. A. Bobrov, E. V. Vilshanskaya, B. B. Zelener Joint Institute for High Temperatures, Russian Academy of Sciences, Moscow Abstract: We discuss coherent narrow resonances in a homogeneously broadened profile of selective reflection from interface between a cell window and high-density atomic rubidium vapour, where the dipole broadening is… Read More »

Instability of higher-order optical phase and polarisation singularities in a homogeneous linear medium

N. N. Rosanov Ioffe Institute, St. Petersburg Abstract: We analyse the behaviour of the instability development of the monochromatic beams with higher-order singularities in a homogeneous isotropic linear medium. A comparison with the case of nonlinear media is made, and the possibility of the experiment is discussed. Keywords: Gaussian beams, wavefront dislocations, polarisation singularities Received: 17.11.2022… Read More »
