| 摘要 |
The invention relates to an electro-optical modulator, comprising at least one optical waveguide (112, 122); an electrode arrangement (1) for applying a voltage across the optical waveguide (112, 122), wherein the electrode arrangement (1) comprises a first and a second electrical line (11, 12) and at least two terminating resistors (21, 22) terminating the first and the second electrical line (11, 12); and wherein the electrode arrangement (1) comprises at least one capacitive structure (31) that capacitively couples, but galvanically separates the two terminating resistors (21, 22). According to the invention, the capacitive structure (31) comprises at least two electrically conductive layers (313, 314, 316) physically arranged at a position between the first and the second electrical line (11, 12), wherein the at least two layers (313, 314, 316) are separated by at least one dielectric layer (315, 317). |
