Research paperExperimental CharacterizationUltrabroadband thin-film lithium tantalate modulator for high-speed communicationsChengli Wang, Dengyang Fang, Junyin Zhang, Alexander Kotz et al.arXiv·2024·10.1364/OPTICA.537730·arXiv:2407.16324AbstractWe demonstrate an integrated thin-film lithium tantalate Mach-Zehnder modulator with a measured electro-optic 3 dB bandwidth of approximately 110 GHz and a half-wave voltage-length product of 2.8 V·cm. The device supports 176 GBd PAM₈ transmission at net data rates exceeding 400 Gbit/s and exhibits lower bias drift than a comparable lithium niobate modulator. We also show that silver electrodes reduce microwave losses relative to gold electrodes.Read more
