5th International Symposium for Optical Interconnect in Data Centres

Co-Located with 43rd European Conference on Optical Communication (ECOC 2017)

Date: Tuesday, 19th September 2017

Location: Meeting Room J2, ECOC Exhibition 2017, Gothenburg, Sweden

The symposium is focused on high-performance, low-energy and cost and small-size optical interconnects across the different hierarchy levels in data center.We intend to draw out and discuss the key technology enablers and inhibitors to widespread commercial proliferation of photonic interconnect in “mega” data centre environments and how the optical interconnect community can collectively help to address these.
The topics addressed will centre on passive and active embedded photonic interconnect technologies including optical circuit boards, polymer and glass waveguides, III-Vs, silicon photonics, photonic crystals and plasmonics in data centers.

PhoxTroT’s 2nd Summer School on Optical Interconnects



PhoxTroT’s 2nd Summer School on Optical Interconnects

L3MATRIX supports PhoxTroT’s 2nd Summer School on Optical Interconnects at University of St. Andrews.

1st-4th of August 2016.

Co-organized by the Fraunhofer Institute for Reliability and Microintegration (Fraunhofer IZM) and Seagate Technology in the frame of European ICT Project PhoxTroT, the summer school focuses on high-performance, low-energy and low-cost optical interconnects across the different hierarchy levels in data center and high-performance computing systems. There will be a wide range of participants from leading industries and universities around the globe, as well as lectures about striking topics. The lectures will focus on several subjects, all related to the newest important questions about optical interconnects. You will find themes such as Applications, On-board interconnects, On-chip Interconnects and CMPs, On-chip interconnects and Photonic Integration Technologies and also lectures coming from the Industrial perspective.


L3MATRIX Kick-Off in Berlin

The project L3MATRIX  “Large Scale Silicon Photonics Matrix for Low Power and Low Cost Data Centers” started on December 1, 2015.

The kick-off meeting was held on February 22-23, 2016 at Fraunhofer IZM in Berlin.
