Project description
Improving access to Kerr comb generators
Chip-scale Kerr comb generators are an innovative class of light source with massive potential for various uses ranging from LiDAR and high-resolution spectroscopy to ultra-broadband signal processing and hyper-scale optical communications. However, Kerr combs remain unused by commercial products due to the commercial unavailability of high-performance comb generators and the lack of required tools. In this context, the EIC-funded CombTools project aims to develop a robust technology base and ecosystem for fully utilising Kerr combs in relevant fields. The project will create necessary technologies for improved efficiency, offer low-barrier access to comb generators to foster innovation and establish crucial tools for their operation. Finally, it will increase commercial access through collaboration with a selected consortium.
Objective
Chip-scale Kerr comb generators have emerged as a novel class of light sources with disruptive potential for a variety of applications such as hyper-scale optical communications, LiDAR, high-resolution spectroscopy, or ultra-broadband signal processing. Still, Kerr combs have not yet found their way into commercially relevant applications. This is mainly caused by the fact that high-performance comb generators are currently not available as commercial products. Another obstacle is the lack of additional tools that are needed for comb-based signal processing.
CombTools aims at overcoming these obstacles by establishing a powerful technology base and a corresponding ecosystem for leveraging the full potential of Kerr combs in highly relevant application fields. On the technology level, we will develop copper-contamination-free silicon-nitride photonic integrated circuit with record-low propagation loss. Based on this, CombTools will offer low-barrier “democratized” access to comb generators with unprecedented performance, thereby preparing the ground for many follow-up innovations. We will further establish dedicated tools for comb-based signal processing, comprising comb-line processors, arrays of advanced electro-optic modulators, and control modules for comb synchronization. The performance of the developed technology will be shown in a series of ground-breaking demonstrations.
CombTools brings together a carefully selected consortium that covers proven competences in technology, product engineering, and business development. The project can rely on a strong technology base developed by the group of Tobias Kippenberg at EPFL. This technology has been licensed to the high-tech start-up Deeplight, bringing Kerr-comb technology to the market through its German subsidiary Deeplight GmbH. The consortium further comprises Nokia as a leading international player, thereby offering an ideal framework for industrial innovation and entrepreneurial activities in the EU.
