While the Fat-Tree network topology represents the dominant state-of-art solution for large-
scale HPC networks, its scalability in terms of power, latency, complexity, and cost is …

Data center networks are experiencing unprecedented exponential growth, mostly driven by
the continuous computing demands in machine learning and artificial intelligence …

Fast optical switching (FOS) is the most promising technology for data center networks
(DCNs) to meet data rate requirements beyond 800 Gb/s, considering its transparent …

The rapid increases in data-intensive applications demand for more powerful parallel
computing systems capable of parallel processing a large amount of data more efficiently …

We demonstrate an elastic multi-wavelength selective switch with up to two wavelength
switching capability per crosspoint. We fabricated the switch in a silicon photonics foundry …

Due to the advantages of optical circuit switching (OCS), all-optical data center networks
(DCNs) have attracted intensive research interests recently. Hyper-FleX-LION is a highly …

In this review paper, we present an elaborate discussion on wavelength selective switches
and their demonstrations. We also review packaging and electronic photonic integration of …

In this Letter, we present a new hybrid broadband-crossbar switching network that can
switch multiple wavelengths on demand and can also multicast. This switch fabric is an …

Abstract Silicon nitride (Si 3 N 4) arrayed waveguide gratings (AWGs) have been widely
used for dense wavelength division multiplexing systems because of their low loss and …

This paper presents a cognitive flexible-bandwidth optical interconnect architecture for
datacom networks. The proposed architecture leverages silicon photonic reconfigurable all …
