31/07/2020 – Update on recent publications

The current circumstances indeed took a toll on how research is carried out, not only on the Fun-COMP project collaborators, but on a global scale.
Nevertheless, we’ve been able to continue our work, solving or working around the various issues the social distancing compels to tackle.
The list of recent publications from the researchers collaborating to this project proofs the dedication and commitment to their work. We’d like to share their success, and congratulate with each one of them for their accomplishments.

A note of merit goes to Xuan and Johannes, which along with their research partners published extremely interesting results concerning the investigation of the potential and scalability of the Non-von Neumann optical unit cell.

Xuan’s work investigates the behavior and potential range of applications of the NvN unit cell on different photonic platforms: silicon, and silicon nitride. The results help to identify the issues and advantages deriving from the adoption of either of the concepts, which is of high importance for the foreseeable future of the research project.

See 10.1364/OPTICA.379228 to view the full manuscript.

Johannes’s work explores the scalability of the NvN unit cell as a memory platform towards realistic scenarios. In particular, the authors developed a test photonic device capable to store and retrieve in an all-optical fashion up to 512 bits, implementing 256 individually addressed unit cells.

See 10.1109/JSTQE.2019.2956871 for further details.
