examine in this paper two cases, which are very interested for the theory and
experiments: a case of an integrated-optical waveguide with statistic surface
roughness and a case of optical nanofibers with random rough surface. The peculiarities
of approximate solutions of vector electrodynamic problems in the
first cases in brief are discussed and useful
evaluations of losses due to scattering also are given. Some results
of research of radiation losses of optical nanofibers in assumption of Gaussian
statistics of distorted glass/air interface are presented. In conclusion we mark a problem of synthesizing
of an optical processor or/and optical sensor with high metrological parameters with allowance for the problem of
light scattering in optical waveguides with surface roughness.
