Polariton will participate in the 2025 Optical Fiber Communications Conference and Exhibition (OFC), the leading global event for optical networking and communications, attended by over 13,500 professionals from 83+ countries. As part of our efforts to advance optical communication, we are working to bring 400G per lane to 1.6T and 3.2T transceivers.
In parallel, we have achieved a major milestone in electro-optic (EO) modulation. Together with ETH Zurich and the group of Prof. Juerg Leuthold, we fabricated devices which have been demonstrated capable of EO bandwidths around 1 THz. This breakthrough paves the way for next-generation photonic integrated circuits (PICs), 6G networks, and ultra-broadband applications in wireless communication, sensing, and more.
Where: Moscone Center, San Francisco, USA, booth 4042

We successfully measured 400G (200 GBd PAM4) eye diagrams for 3.2T transceivers supporting the next generation of datacenter and AI cluster connectivity. Polariton’s plasmonic modulator technology provides an electro-optical bandwidth beyond 145 GHz, enabling 224 GBd and beyond, which is crucial for target line rates of 448 Gbit/s. While plasmonic modulators have no inherent speed limitations, achieving open eyes at these extreme rates depends on the next generation of high-speed signal generators.
We offer a highest bandwidth, low-footprint, scalable and low-cost solution for sub-THz wireless communication links. We employ a plasmonic-graphene approach. The solution is tested for transmission of 120 Gbit/s at a carrier-frequency of 285 GHz.
