Description
Manuel Kohli and co-authors unveil a photonics platform that marries low-loss silicon nitride circuits with a strongly responsive crystal, reaching modulation speeds past 200 gigabaud. Their 2025 paper serves the push toward terabit fiber links and AI hardware. The active material is barium titanate, squeezed into nanoscale plasmonic guides.
The modulators hit bandwidths up to 110 gigahertz in active lengths as short as five micrometers. Three devices headline the work. A Mach-Zehnder modulator ran at 256 gigabaud. An IQ modulator ran at 224, the first of its kind on this base, and a racetrack design hit 200 in a second band. Data rates reached 448 gigabits per second with the IQ device. The platform also keeps the passive parts the nitride base is prized for.
