Abstract

We present a scalable and novel modular optical metro core node architecture and low cost metro access node architectures with edge computing functionalities employing photonic WDM integrated switches. Photonic integrated switches has been designed as the building blocks to realize the modular metro node architectures, namely photonic WDM switches with express and add/drop ports, photonic integrated WSS aggregation/disaggregation functions for merging/dropping the network traffic, and photonic integrated multi-cast switch (MCS), as well as bandwidth variable transceivers aggregators to achieve multi-Terabits/second operation. Moreover, a dynamic re-configurable metro-access nodes based on low-cost 2-degree photonic integrated mini-ROADMs will be discussed. The lossless photonic WDM switches are based on InP technology and employ semiconductor optical amplifiers as on-chip gain element and fast
switch. The photonic WDM circuits allows to switch multiple format data signals in wavelength, space, and time for full flexibility, scalability of the interconnected network elements as well as capacity. Applications to data center interconnects and 5G will be discussed and experimental results reported.
