Terabit-scale wavelength-multiplexed transmitter enabled by thin-film lithium tantalate

Artificial-intelligence systems face a growing data-movement bottleneck and require higher interconnect bandwidth without a proportional increase in electrical power consumption or the number of laser sources and fibre connections. Moving optical interfaces closer to computing chips reduces electrical transmission loss...

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...
