Theory of laser radiation scattering in integrated optical waveguide with 3D-irregularities in presence of noise: vector consideration

Abstract

Vector theory of the waveguide laser irradiation scattering in an integrated optical waveguide with 3D-irregularities in the presence of a noise is described. For simplification of the analysis of the problem we neglected cross-correlation connections, both between irregularities of the boundaries of the waveguide, and between irregularities of the boundaries and heterogeneities of the refraction index of waveguide mediums. The approximate solution of inhomogeneous three-dimensional wave equation is derived by the Green function method. The analytical formulas of the radiating fields for the propagating and evanescent modes are fined. Physico-mathematical interpretation of derived expressions is given.

Properties of liquid-crystal wave-guiding structures

“…Expression (3) describes TE radiation modes at a high signal-to-noise ratio. 15,26,27 For TM modes, the solution is obtained similarly to eqn (3). A description of the features of the algorithm given below and some results of numerical modelling are given in ref.…”

“…The list of required literature on this topic and related areas can be easily expanded by citations in the indicated publications. 1–33 From this point of view, of undoubted interest is, for example, the review. 18 At the same time, it should be emphasized that it is really possible to give a detailed analysis of the development of the situation in the actively developing field of science and technology only in a special review.…”

Numerical investigation of characteristics of laser radiation scattered in an integrated optical waveguide with three-dimensional inhomogeneities

“…For those who want to learn the details of the effect of three dimensional vector scattering, we recommend publications [5][6][7][8][12][13][14][15][16][17][18][19][20][21][22][23] and references therein.…”

“…Solution of the three dimensional (3D) problem of electrodynamics [3,[5][6][7][8][13][14][15][16][17][18][19][20][21][22][23] is of great impor tance for the development of both new numerical methods of investigation [15][16][17][23][24][25] and new experimental methods and technologies of waveguide photonics [23][24][25][26][27][28].…”

Side-scattering properties of a novel waveguide multilayer memory

“…Although side-scattering properties of optical fibers and optical slab waveguides have been studied and corresponding experiments have been done, [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22] such studies of multilayer waveguide memories are seldom reported. We investigate this problem by building a simplified model.…”
