The electrode structure comprises in each section three parallel microbands of identical width, the first and second microband covering first and second optical guides respectively and being separated by a width giving to the propagating line which they form a characteristic impedance equal to the required adaptation impedance; the third microband is far enough away from the second band for the contribution of the former to such characteristic impedance to be negligible. The covering of the first and second optical guides by the first and second microbands alternates from one section to the next section and the passage from a first section to a second section is obtained by a transition zone comprising inclined microbands.
