Сверхразрешение при восстановлении профиля диэлектрической проницаемости оптического волновода по дальнему полю излучения моды

Abstract

The algorithm of analytical continuation of Foyrier transform of an optical waveguide mode field is proposed. The algorithm is shown permits to reconstruct the permittivity profiles of optical fibers and channel waveguides from the mode far field pettern with subwavelength resolution.
