Lightwave Logic and Polariton Technologies Announce World-Record Performance for 250 GHz Optical Link

PR Newswire

Breakthrough Peer-Reviewed Paper Results Presented at Prestigious 2022 European Conference on Optical Communications (ECOC)

ENGLEWOOD, Colo. and RUSCHLIKON, Switzerland, Sept. 22, 2022 /PRNewswire/ — Lightwave Logic, Inc. (NASDAQ: LWLG) and Polariton Technologies today 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 groundbreaking results were presented by Stephan Koepfli as part of a peer-reviewed post-deadline paper presented at the prestigious 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 bandwidth2.

Dr. Michael Lebby, Chief Executive Officer of Lightwave Logic, said: “Next generation ultra-high-capacity interconnects require compact, ultra-fast modulators on the transmission end and ultra-fast photodetectors on the receiving end – this incredible result demonstrates that our electro-optic polymers will be instrumental not only for next-generation high-capacity interconnects, but for the more advanced and faster links that will be required for succeeding generations. This is an optical link that utilizes devices with extremely high bandwidths, and the plasmonic demonstration shows that hybrid technologies such as electro-optic polymers and graphene together form an important technology platform for volume scalability using large silicon foundries for mass commercialization. Through our collaboration with Polariton, we have utilized our polymers for a world-record performance for a plasmonic optical link.

“The plasmonic-to-plasmonic optical link opens flexible integration possibilities that we have only imagined before. This shows that plasmonic devices now complete an ultra-high frequency toolbox for a variety of applications in fiber communications – something we need to add to our technology roadmaps going forward,” concluded Lebby.

Dr. Wolfgang Heni, Co-CTO at Polariton, added: “Polariton is dedicated to providing best-in-class devices with the highest-performance. Our goal is to make optical communications faster, the technology more scalable and with it, components and infrastructure more energy efficient. ETH Zurich’s recent demonstration of a plasmonic link using both electro-optic polymers and graphene as active materials provides a peek into the future of super high-capacity optical networking. This showcases the opportunities of integrating advanced materials with established photonic platforms such as silicon photonics.”
