Integrated thin film Lithium niobate modulator with Segment interleaved electrode
Abstract:Integrated thin film Lithium niobate modulator is easy to integrate in silicon-based photonic platform because of its low loss, high bandwidth and low half-wave voltage characteristics.It has high application value in the field of optical communication and photoelectric chip integration.According to the requirements of low half wave voltage and high bandwidth, a segmented staggered traveling wave electrode is proposed, which effectively reduces the microwave loss and then the half wave voltage.The simulation results show that the half wave voltage reaches 1.54v at 0ghz, the half wave voltage reaches 2V at 40GHz and the bandwidth reaches more than 60GHz;Compared with the traditional GSG electrode under the same conditions, the half wave voltage is reduced by 19.2% at 40GHz.
Keywords: LiNbO3 modulator Segmented electrode Half-wave voltage Transmission line analogy
