Abstract

The coupler has an interaction region 8L1) with waveguides (3,4) and an electrode. The interaction region (L1) is divided into two sections (S1,S2) with a central electrode (6,9) and two outer electrodes (5,7;8,10) in each section. Voltage sources (12,13,14; 15,16,17) are connected to the electrodes and generate electrical fields through the waveguides (3,4). The electrical field between the outer electrodes (5,7; 8,10) has in each section (S1,S2) the same direction in both waveguides (3,4). The electrical field between the central electrode (6;9) and outer electrodes (5,7;8,10) has mutually reverse direction in both waveguides in the sections (S1,S2).
