ALLEGRO aims at designing and validating a novel end-to-end sliceable, reliable, and secure architecture for next-generation optical
networks, achieving high transmission/switching capacity -- with 10 Tb/s for optoelectronic devices and 1 Pbt/s for optical fiber
systems --; low power consumption/cost -- with > 25% savings -- and secure infrastructures and data transfers. The architecture relies
on key enabling innovations: i) smart, coherent transceivers exploiting multi-band & multi-fiber technologies for P2P and P2MP
applications, based on e.g., high-speed plasmonic modulators/photodetectors and programmable silicon photonic integrated waveguide
meshes; ii) loss-less, energy-efficient transparent photonic integrated optical switches, eliminating OEO conversions, e.g., with on-chip
amplification in the O-band for datacom applications; iii) a consistent approach to security, in terms of functional/protocol architectures
and communications, further improving QKD systems, enabling optical channel co-existence and researching on quantum-resistant (postquantum) cryptography, developing systems based on physically unclonable functions; and iv) a scalable AI/ML assisted control and
orchestration system, responsible for autonomous networking, dynamic and constrained service provisioning, function placement and
resource allocation, leveraging devices increasing programmability and overall network softwarization. To achieve the target objectives
and KPIs, ALLEGRO has defined a clear methodology ending in ambitious demonstrators. The consortium includes a good balance
of industry and research/academia with know-how in complementary fields. The results of ALLEGRO will be disseminated in leading
conferences, events, and high-impact journals. They will have a concrete and measurable economic and social impact, contributing
towards achieving key European objectives, reinforcing European leadership and digital sovereignty in the ongoing digital and green
transition.
