The performance increase of established Von Neumann computing systems has been defined by the scaling of silicon chip technology according to Moore’s law as well as advances in assembly and system integration concepts. While these scaling paths run into technological and commercial challenges, these types of systems are not well suited to process the enormous amounts of unstructured data generated nowadays. The hardware requirements for neuromorphic computing systems will be discussed, introducing the concept of in-memory computing and analog synaptic signal processing. Massive performance and power-efficiency enhancements in neuromorphic computing are feasible but stringent requirements on the technology platform must be adhered to. Photonic technologies and signal processing concepts offer good potential to address this challenge, as will be discussed in this seminar.



Bert Offrein received his Ph.D. degree in nonlinear integrated optics from the University of Twente (NL) in 1994. He then joined IBM Research - Zurich and contributed to establishing and commercializing adaptive integrated optical technology for DWDM networks. From 2004 to 2016, Bert Offrein was managing the photonics group, addressing optical interconnects for computing systems. Since 2016, he is leading the neuromorphic devices and systems group, focussing on novel hardware for neural networks. Bert Offrein is a principal research staff member at IBM Research and the co-author of over 150 publications and the co-inventor of more than 35 patents.
