In today’s information age, new applications like 5G, Internet of Things, or cloud computing rely strongly on an efficient communication infrastructure. The backbone of this infrastructure is the high-bandwidth optical communication network. However, the ever-increasing data traffic brings this network to its limits. One main bottleneck are the so-called electro-optic modulators. They convert the electrical data from the servers onto the optical fibres used for information transport. Today’s electro-optic modulators cannot deliver the speed required for future high-speed communications; they are too large in footprint and hence expensive in fabrication, and energy inefficient. All of this is caused by the photonic nature of current electro-optic modulators.
Polariton Technologies's objective is to overcome the current bandwidth limitations in telecommunications and sensing applications. By delivering the world's fastest and smallest modulators, we enable high-speed communication at unprecedented speed, with lowest footprints, costs and energy consumptions. This way, we relieve telecommunication system vendors from the pain of the optical interconnect bottleneck: the demand for data traffic is rapidly growing, while the speed-growth of their optical communication networks cannot keep up.
Was ist das Besondere an diesem Projekt?
Polariton Technologies Ltd.’s plasmonic electro-optic modulators overcome this limitation by relying on plasmonics rather than photonics. Based on a scientific breakthrough at ETH Zurich, we could demonstrate plasmonic modulators that are more than 10-times faster than current modulators (500 GHz world record in the lab). Moreover, our modulators are 100-times more compact, more energy-efficient, and potentially cheaper in production. Our technology is the urgently needed technological step overcoming the electro-optic bottleneck. We enable the optical communication infrastructure to catch-up with the impressively growing demand for data transport.
We are currently focusing on building a new prototype, before validating it in a field demonstration. We are searching for packaging partners, talented students to join our team and external investment by end of 2019.
