✦ Synopsis

The phenomenon of the waveguide mode scattering in the
irregular planar optical waveguide is investigated. The solution
of the direct problem is fined with the help of the theory of
perturbations. The inverse waveguide scattering problem consists
in restoring of autocovariance function and determination of
irregularities' parameters by the measuring data of scattering
diagram in the far zone. The computer simulation allow approving,
that our method permits to receive an approximate correct solution
of the inverse problem with the rms error of restoring of the
given autocovariance functions no more than 35% in the presence
of high real noise (for SNR ≥ 1). The statistic parameters
of irregularities in this case are determined with the error less
than 15-30 %.

The finite difference in the frequency domain (FD-FD) method is used here to analyze the propagation characteristics of a lossy dielectric waveguide. These characteristics are optically controlled by means of light incidence on a semiconductor layer positioned on the dielectric waueguide. In the for
