摘要
This paper presents we added a feedforward circuit to improve the signal quality by adding a feedforward circuit to the third-order distortion caused by increasing the modulation index of the LiNbO3(LN) optical modulator, and described its effect. Furthermore, we applied this optical modulator distortion reduction experimental device using this feedforward to a 5-channel simultaneous BS television information signal modulation system, and described its characteristics. © 2024 The Institute of Electrical Engineers of Japan.
