H2020-MASSTART Project is proudly contributing to the Photonics Days Berlin Brandenburg 2020 organized by OpTecBB with a dedicated conference session on "Data Center Interconnects - Towards mass manufacturing", chaired by Benjamin Wohlfeil (ADVA) & Paraskevas Bakopoulos (Mellanox Technologies / NVIDIA).
A holistic transformation to the assembly and characterization of high speed photonic transceivers is required towards bringing the cost down to €1/Gb/s or even lower in mass production. The cost metric threshold can be addressed by using enhanced and scalable techniques, such as
• glass interface based laser/PIC and fiber/PIC coupling approaches, leveraging glass waveguide technology to obtain spot size and pitch converters in order to dramatically increase optical I/O density,
• while facilitating automated assembly processes,
• 3D packaging (TSV) enabling backside connection of the high speed PIC to a Si carrier,
• a new generation of flip chip bonders with enhanced placement in a complete assembly line compatible with Industry 4.0 which will guarantee an x6 improvement in throughput and
• wafer-level evaluation of assembled circuits with novel tools that will reduce the characterization time by a factor of 10, down to 1 minute per device.
Such process flow is assessed with the fabrication and characterization of demonstrators, addressing the mid-term requirements of next generation transceivers required by Data Center operators and covering both inter- and intra- Data Center applications. These demonstrators are:
• a 4-channel PSM4 module in QSFP-DD format with 400G aggregate bit rate,
• an 8-channel WDM module in a QSFP-DD format with 800G aggregate bit rate,
• a 16-channel WDM on-board module delivering 1.6Tb/s aggregate line rate and
• a tunable single-wavelength coherent transceiver with 600Gb/s capacity following the DP-64QAM modulation format on 64Gbaud/s line rate.
The first half of the session is dedicated to high level to introduction of the system perspective, as well as focus on the main topic of the session which is the automated assembly.
All MASSTART technology building blocks will be presented in the second half of the session together with the overall packaging solution.
This conference session is organized in cooperation with MASSTART Consortium and OpTecBB.
