Abstract
An optical transmission device comprises a lithium niobate modulator and a laser. The lithium niobate modulator includes an input optical fiber configured to receive the initial optical signal, an optical splitting element configured to split the initial optical signal to generate two optical splitting signals, two optical splitting paths configured to transmit the two optical splitting signals, a radio-frequency signal channel disposed in parallel between the two optical splitting paths and configured to transmit a radio-frequency modulation signal, a ground channel disposed in parallel with and connected to the radio-frequency signal channel, an optical combining element configured to combine the two optical splitting signals to generate an optical modulation signal, and a output optical fiber configured to output the optical modulation signal. The radio-frequency signal channel and the ground channel are used in modulation of the two optical splitting signals in accordance with the radio-frequency modulation signal.
