Following the tradition of previous editions, ONDM 2023 will address cutting-edge research in optical networking in support of a wide variety of new services and applications. This includes the most recent trends such as: 5G and beyond; data-centre networking; Internet of Things; cloud/edge computing; content delivery networks; data analytics, network telemetry and real-time monitoring; autonomic networking; artificial intelligence / machine learning assisted networks; visible light communications; and Quantum Internet.

Such trends drive the need for increased capacity, efficiency, flexibility adaptability and intelligence in the functions that optical networks must perform in the next years. In turn, these challenging needs can be addressed by developing new optical network architectures, based on different optical network disaggregation models, exploiting and integrating novel multidimensional photonic technologies as well as by adopting open and highly programmable hardware and software platforms such as software-defined networking (SDN) and network function virtualization (NFV). The ultimate goal of such network revolution is to enable new business models and opportunities for network operators and their customers. The scope of the conference includes but is not limited to the following topics related specifically to optical devices, systems, and networks:

• Advances in optical network modelling and optimization
