Novel technologies related to optical communications, sensing, the Internet of Things (IoT) and artificial intelligence have been generating unique opportunities and potential to enhance our quality-of-life, and to provide new services for our society and economy. However, the perspective to manage and process the dramatically increasing amount of data relies on our ability to handle these data with high-speed, suitable hardware and much improved energy efficiency.
In this project, it is our aim to develop novel all-optical decoding schemes for optical communication networks that are based on neuro-inspired concepts and are able to fulfill the previous requirements.
Excellently performing neuro-inspired concepts and algorithms, in particular related to machine learning, have been developed, but their energy requirements and lack of speed hinder their implementation in a significant number of current and future applications. In particular, this approach faces severe challenges, when trying to apply it in all-optical communication networks.
Hence, in this proposal we follow a different approach, building upon our experience of designing and realizing neuro-inspired information processing systems, mainly in photonic hardware. In contrast to traditional machine learning, we replace the usual structure of a network composed of multiple connected nodes by a simple dynamical system. The latter comprises a nonlinear node subject to delayed feedback, exploiting the dynamical richness of the delay systems for computational purposes. We aim at extending these concepts by introducing novel pre-processing techniques, taking advantage of multilevel systems and applying novel learning concepts adapted to the particular data and processing requirements. To mitigate the risk, our approach could also be applied in the electronic domain after the signal detection.
The guiding principle will be the realization and implementation of data decoding techniques that combine conceptual and hardware simplicity, high-speed, flexibility, energy efficiency and high performance.
Altogether, this project represents an important step towards ultra-fast, energy-efficient data decoding techniques, complementary to standard approaches. It promises the identification of minimum requirements and the implementation of the concept with high performance. Ultimately, it serves a digital society, in which technology is harnessed to improve data handling and processing and to provide new services.
