1. Recent progress in IOWN APN: Use case and enabling technology development
In recent years, there has been extensive progress toward All-Photonics Network (APN) that is one of the major technological fields that comprise IOWN. Because of its high-capacity, low-latency, and high-energy efficiency features, the APN provides an exceptional communication environment, which can lead to various business opportunities. In this talk, recent efforts will be reviewed in the APN context, including use case and enabling technology development. Specifically, potential impact on data center operation and opportunities for further enrichment of remote/online activities are highlighted. Moreover, novel optical node systems, photonic exchanges (Ph-EXs) and photonic gateways (Ph-GWs), and their related technologies are introduced.

2. Automatic network operation based the optical network digital twin
​​​​To achieve high-capacity and low-latency Open All-Photonic Network, it is necessary to develop core technologies such as optical wavelength path quality estimation and optical path visualization. In this presentation, we show the research and development trends aimed at automatic operation technology that can achieve optical wavelength path provisioning and rapid fault localization by integrating them on an optical network digital twin platform with a simulation function for virtual facilities. We also show our field trial results with the open and disaggregated transponders that enable cloud-native operation.

3. Encrypted communication technology for quantum computer era
Encrypted communication with post-quantum security will be essential for next-generation networks such as All-Photonic Network (APN). In this presentation, we will introduce NTT's Encrypted communication technology that achieves post-quantum security and high crypto agility without compromising network performance in the quantum computer era. The presentation will also discuss the PoC of applying this technology to a data backup use case using international APN line between Taiwan and Japan and NTT's vision for end-to-end data security, including the computing environments to which the APN is connected.

4. Photonics-Electronics Convergence (PEC) device technology for IOWN
Optical transmission has made it possible to increase the speed, reduce the power consumption, and extend the distance of data transmission. The key to IOWN realization is to utilize the light for not only data transmission but also data processing. In this presentation, we introduce a small optical transceiver and optical chiplet that can be applied to inter/intra package optical interconnect .
