| Zusammenfassung: | The invention relates to an electrooptical modulator comprising a substrate, an optical waveguide, a first modulation electrode component and a second modulation electrode component. The optical waveguide comprises a Y-shaped incidence part, a Y-shaped emitting part, a first connecting part and a second connecting part, wherein the first connecting part is used for transmitting transverse electric waves only and the second connecting part is used for transmitting transverse magnetic waves only. The first connecting part is connected with the Y-shaped incidence part and the Y-shaped emitting part and comprises a first branch and a second branch. The second connecting part is connected with the Y-shaped incidence part and the Y-shaped emitting part and comprises a third branch and a fourth branch. The first modulation electrode component comprises a first ground electrode, a first modulation electrode and a second modulation electrode, wherein the first ground electrode is arranged between the first branch and |
