Our world is filling with digital devices that communicate with each other. Also, modern lifestyle allows people to exchange more and more data via the Internet. The data is processed and stored as an electrical signal within a device. Yet, transmission of the data is usually performed with optical signals across an optical fiber. The conversion from an electrical signal to an optical signal is performed by modulators. Modulators are thus key components in today's communication infrastructure. The competence of Polariton Technologies is to shrink the size of these modulators down by a factor of more than one hundred, while increasing the speed by a factor of ten and reducing the energy consumption.
What is special about the project?
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.
