Electro-optical modulator

An electro-optical modulator, comprising

• a first and a second optical waveguide;
• at least one first capacitance (C1, C1a-d), via which a voltage can be applied to a light-guiding region of the first optical waveguide;
• at least one second capacitance (C2, C2a-d), via which a voltage can be applied to a light-guiding region of the second optical waveguide;
• an electrically conductive region, via which the first and second capacitances (C1, C1a-d, C2, C2a-d) are electrically connected to one another;
• and
• a feed line to the electrically conductive region, via which feed line a DC voltage can be applied to the electrically conductive region, wherein the feed line is constituted such that it represents an electrical resistance (Rn_acc) connected in parallel with the second capacitance (C2, C2a-d);
• and
• a compensation resistance (Rn_comp) connected in parallel with the first capacitance (C1, C1a-d) and serving for reducing transients in a voltage profile on the first and second capacitances (C1, C1a-d, C2, C2a-d) during the operation of the modulator,
• wherein the compensation resistance (Rn_comp) is dependent on the first capacitance (C1) or, in the case of a plurality of first capacitances (C1a-d), on a first total capacitance C1tot, the resistance (Rn_acc) of the feed line and the second capacitance (C2) or, in the case of a plurality of second capacitances (C2a-d), on a second total capacitance (C2tot), wherein the product Rn_comp·C1 or the product Rn_comp·C1tot lies in the interval (Rn_acc·C2)+−20% or (Rn_acc·C2tot)+−20%.
