Demonstration of Non-Symmetric Thin-Film Lithium Niobate Modulator with a 3-dB Bandwidth Beyond 100 GHz

Thin-film lithium niobate electro-optic modulators with bandwidths >100 GHz are demonstrated. The trade-off between bandwidth and voltage is alleviated by non-symmetric positioning of waveguides with respect to electrodes and by incorporating a dielectric buffer layer.
