120 GHz Sub-2 V Thin-Film Lithium Niobate Modulators on Silicon Substrate Using Thick Capacitively Loaded Slow Wave Electrodes

Electro-optic modulators with large bandwidth and low voltage are crucial for the high-baud-rate digital communication and high-carrier-frequency analog links. Recently, thin-film lithium niobate (TFLN) modulators with sub-1 V voltage and 140 GHz bandwidth have been emerged on the low permittivity s...
