Abstract
A multilayer structure (S,1-3) is surmounted by parallel primary lines (4-1, 4-2) which define, in the regions situated below them, waveguides operating according to a first propagation mode. At least one electro-optical control means (E-1) is placed at a selected location between each pair of primary lines and, under certain conditions, enables the local existence of a second propagation mode affecting the two regions together, so that the transfer of the first mode between the two guides which enclose it can be controlled by acting on the second mode. This makes it possible to produce an energy distributor based on a so-called 'cascade' architecture.
