High-efficiency slow-light modulator on thin-film lithium tantalate operating at high optical power.

Integrated electro-optic (EO) modulators are essential interfaces between electrical and optical signals, but maintaining high modulation efficiency and broadband EO response under high optical power remains challenging. Here, we demonstrate a thin-film lithium tantalate (TFLT) Mach-Zehnder modulator combining 1-mm-lon...

Beyond 110 GHz Electro‐Optic Slow‐Light Modulation via Cascaded One‐Dimensional Topological Edge States on Thin‐Film Lithium Tantalate

High‐speed and broadband electro‐optic modulators are crucial for next‐generation optical interconnects, yet conventional designs face a trade‐off between modulation bandwidth and efficiency. Here, we exploit and implement superlattice structures on thin‐film lithium tantalate to achieve slow‐light‐enhanced electro...
