[ECOC 2016] The importance of Microelectronics and Photonics Convergence

The 42nd edition of ECOC – European Conference on Optical Communications, this year in Dusseldorf (18-22 September), focused on the convergence of Photonics and Microelectronics to develop cost-efficient next-generation optical networks. One of the most important conclusions pointed out during the plenary session was that both content providers (generation and processing) as well as transport service providers are driving forward the development of innovative technologies for efficient networking.

Although in different technology readiness levels, the speed requirements for the data generation and processing inside the IP routers grow much faster  than the speed evolution in photonic transport networks, 60% against 20% per year, respectively. And the only available degree of freedom to be fully exploited is the Space. Although this might be relatively far from becoming a reality, I have to agree that parallelism is the only solution to scale the transport speeds to cope with the data rate demands.

Using or not space-division multiplexing, future line interface speeds can only scale efficiently taking the best of the two worlds, i.e. Photonics (Integrated Devices) and Microelectronics (DSP-ASICs) growing together. The basic building blocks inside any optical transceivers can meet the performance and cost requirements when built together. This exactly what drives our roadmap here in CPqD. We showed during ECOC 2016 some of the key enabling technologies exploiting the best of photonic integration and signal processing for future high-capacity flexible optical systems.
