Ultrabroadband, Subvolt Thin‐Film Lithium Niobate Modulators via Codesigned Optical and RF Slow‐Wave Structures
Low‐voltage, high‐bandwidth electro‐optic modulators are essential for next‐generation optical interconnects and CMOS‐compatible photonic systems. Here, we demonstrate thin‐film lithium niobate (TFLN) Mach–Zehnder modulators that combine slow‐light optical waveguides with inductively loaded slow‐wave RF electrodes to s...
