Lightwave Logic, Inc. and Polariton Technologies announced the achievement of a world-record demonstration of a 250GHz super high bandwidth electro-optical-electrical (EOE) link through a collaboration with ETH Zurich. The link was demonstrated by ETH Zurich and uses Polariton's high-speed plasmonic modulators containing Lightwave's proprietary PerkanamineTM chromophores and ETH Zurich's high-speed graphene photodetectors. The results were presented by Stephan Koepfli as part of a peer-reviewed post-deadline paper presented at the 2022 European Conference on Optical Communications (ECOC) in Basel, Switzerland on September 22, 2022.

The post-deadline paper is titled ">500 GHz Bandwidth Graphene Photodetector Enabling Highest-Capacity Plasmonic-to-Plasmonic Links". The link contained a plasmonic modulator using electro-optic polymer material as well as a novel metamaterial enhanced graphene photodetector featuring a 200 nm spectral window and a setup-limited1 bandwidth of 500 GHz. The EOE link achieved a world record and unprecedented 250 GHz 3dB bandwidth.
