ETH Zurich and Polariton Achieve Record-Breaking Electro-Optic Bandwidth with Plasmonic Modulators

Polariton & Lightwave Logic
We announce a collaboration between Lightwave Logic and Polariton Technologies
Industry Voices
We are excited to supply our EO polymer materials and integration expertise enabling Polariton to develop a revolutionary approach addressing the opportunities presented by AI market.
Polariton stands for Swiss Innovation
We provide the world’s fastest, smallest and most energy-efficient photonic integrated circuits (PICs) to leaders in academia and industry. And we do this based on the proven silicon photonics platform and add plasmonics structures achieving a paradigm shift where other technologies saturate. With 20 years of R&D in our genes, Polariton is a spin-off of the Swiss Federal Institute of Technology (ETH Zurich), and is the first company in the world commercializing plasmonics and other slot-based technologies for the next generation of fast, very fast photonic switches.
