Project description:

The POLYCONNECT project focuses on integrating optical polymer waveguides into printed circuit boards (PCBs) to create high-capacity optical interconnects for efficient data transmission in data centers. As global data traffic grows exponentially, wavelength division multiplexing (WDM) Silicon Photonics (SiPho) transceivers are increasingly deployed. However, traditional electric interconnects on PCBs cannot meet the scaling demands of energy efficiency, channel density, and bandwidth. To address this limitation, the project aims to replace electric transmission lines with optical waveguides, which offer superior bandwidth-length product and improved data handling capabilities. The ultimate goal of POLYCONNECT is to demonstrate polymer photonic interconnects for high-density data centers, using line card PCB prototypes that enable low power consumption and high-speed multichannel data transmission.
