Aula Beta (Ed. 24), Politecnico di Millano (Campus Leonardo) 

Chair: Francesco Morichetti, Politecnico di Milano

 

On February 18, Politecnico di Milano (DEIB) will host a seminar dedicated to the role of photonics in shaping the future of AI infrastructures and next-generation wireless communications.

Organized within the framework of the PIX Europe project and promoted by the IEEE Photonics Society Italy Chapter, the event brings together cutting-edge research and real technological challenges at the intersection of optics, computing, and communications.

 

11:00-11:45  High Speed Optical Interconnects for AI infrastructure

Prof. Oskars Ozoliņš, Riga Technical University

Abstract: The increasing computational demands of AI systems require optical interconnects that provide higher bandwidth density, lower energy per bit, and scalable manufacturability. This talk will review recent advances in high-speed optical I/O technologies, with particular focus on next-generation modulator platforms that underpin these interconnects. Silicon photonics highlight their respective advantages for AI-driven performance targets. Emphasis will be placed on system-level experiments, electro-optic optimization, the role of wafer-level characterization, and the integration challenges that must be overcome to support the future scale of AI interconnect architectures. 

11:45-12:30  Free-Space Optical Beamforming for Fi-Wi-Fi Scenarios and Commodity QKD

Dr. Bernhard Schrenk, AIT Austrian Institute of Technology

Abstract: Optical wireless communication is touted as one important contributor to establish a seamless communication-computing continuum within 6G networks – our future communication infrastructure that expands towards a highly heterogeneous landscape that will eventually fuse communication, sensing and quantum technologies. Towards that, key enablers such as optical beamforming will be addressed, with the aim to establish Fi-Wi-Fi bridges for extending the fiber-grade connectivity in fiber-scarce environments, as well as to serve as optical hotspots for solarblind quantum key exchange for handheld smartphone-like applications in the commodity segment.

Free-Space Optical Beamforming for Fi-Wi-Fi Scenarios and Commodity QKD

Biography:

 

AIT-Forscher Bernhard Schrenk erhält ERC Proof-of-Concept GrantBernhard Schrenk is senior scientist at the AIT Austrian Institute of Technology. Prior to his PhD study at UPC Barcelona, he was at the Institute of Experimental Physics of Nobel laureate Prof. A. Zeilinger, where he was involved in the realization of a first commercial prototype for a quantum cryptography system. After a post-doc year at NTUA in Athens, he established his own research group on photonic communications at AIT. He has (co-)authored ~260 publications and has served as TPC member for the OFC and ECOC conferences. His excellent work is recognized by being awarded with ERC Starting and Proof-of-Concept Grants.
