Numeric simulation of the integrated electro-optical intensity modulator on lithium niobate substrate as a part of microwave path

Broadband electro-optic intensity modulators widely used in optical communication lines today. These modulators are used to transform the electrical high frequency signal to the optical signal. The most important characteristics of these devices are the electro-optical bandwidth, the modulation efficiency, the extinction on/off, the chirp, as well as other parameters that characterize the high frequency response of the modulator. This paper presents the results of numerical simulation of the electrical parameters of the modulators for optical communication lines by using different electrode structures and modulator construction generally.
