Abstract: Propagation of light in a circular system of coupled waveguides is studied. The system of cylindrical waveguides is constructed with the help of SPCVD technology used for synthesising optical fibre preforms. It is shown that a 0.63-μm light beam focused at the entrance of a cylindrical system propagates in it with radiation power losses. The radiation is spatially modulated, which makes possible to estimate the period of beam width oscillations inside the waveguide system.
