Plasmonic monolithic transmitter operating beyond 100 GBd

Plasmonic modulators enable the first high-speed monolithic transmitter operating beyond 100GBd. At the 45th European Conference on Optical Communication (ECOC 2019), ETH Zurich researcher Ueli Koch presented the first monolithic high-speed transmitter offering 120 Gbit/s NRZ-OOK integrated on a single chip of only 1.5mm x 3mm, comprising an electronic-photonic layer stack including a 4:1 SiGe BiCMOS multiplexer and plasmonic modulators.  

The groundbreaking work “Monolithic High-Speed Transmitter Enabled by BiCMOS-Plasmonic Platform” accelerates the co-integration of electronics and photonics. This work was made possible by the collaboration of ETH Zürich, Universität des SaarlandesMicram Microelectronic GmbHUniversity of WashingtonMellanox Technologies Ltd., Aristotle University of Thessaloniki (AUTH), and Polariton Technologies Ltd.
