Concept

NEBULA aims to provide the foundations for a common future-proof transceiver technology platform with ultra-high bandwidth capabilities offered by a CMOS compatible toolkit and tailored towards meeting performance, cost and energy metrics in both inter-DCI coherent and intra-DCI ASIC co-packaged optics. In this context NEBULA invests in the established bandwidth- and energy saving credentials of plasmonic modulator solutions together with the functional digital processing portfolio of neuromorphic optical reservoir computing engines, tailoring them in System-in-Package prototype assemblies that can intersect with the challenging framework of both inter- and intra-DCI segments. NEBULA will highlight its technology’s unrivaled combination of benefits by deploying and demonstrating:

  • A fully-functional 8-channel 112Gbaud 16QAM C-band transceiver prototype, with SiN-based Neuromorphic Augmented Reservoir Chip (NARC) that employs CMOS compatible ferroelectric photonic weights, offering an aggregate capacity of 3.2Tbps.
  • A fully-functional sub-Volt 8-channel 112Gbaud PAM4 O-band transmitter co-packaged with a data generating ASIC, offering a 1.6Tbps aggregate capacity.

The NEBULA project is an initiative of the Photonics Public Private Partnership and has received funding from the European Union's Horizon 2020 Research and Innovation Programme under Grant Agreement No. 871658.
