The second NB-Photonics seminar of 2020 will take place on 7th February (in AUD iGent). Dr. Paraskevas Bakopoulos from Mellanox Technologies. will give a talk on “Optical interconnects for datacenter networks"

Dr. Paraskevas Bakopoulos is a senior staff engineer at Mellanox Technologies. His research interests focus on short-reach optical interconnects and optical switching for datacenter networks. Paraskevas received his Diploma and Ph.D degrees from the National Technical University of Athens (NTUA), Greece, where he worked for over a decade as a researcher and senior researcher on various concepts combining  photonic circuit design and system architectures. Paraskevas has authored or co-authored more than 120 peer reviewed articles and conference papers and holds 4 patents. He is actively involved in European research projects and has participated in technical program committees of photonics-related events.

Datacenter networks represent a thriving application field for photonics. Short-reach links deployed inside the datacenter and spanning from a few meters up to 2 kilometers hold the lion’s share, since more than 70% of overall traffic stays within the datacenter. Datacenter interconnects pose compelling challenges to the underlying photonics technology as they have to keep pace with 25% year over year traffic growth as well as to cope with aggressive cost targets. This talk will present the end-user’s perspective on key requirements coming from the application area. We will outline current practices in datacenter networks (optical transceiver types, physical form factors and integration schemes) and we will focus on open challenges and future research trends. We will elaborate on most prominent directions for scaling datacenter networks, i.e. through closer integration of photonics with electronics as well as through extending the functionality of photonics to provide switching in the optical domain. We will also give examples from our ongoing research in collaborative projects that aim to tackle the above challenges.
