The ever-increasing bandwidth requirements of modern datacenters have led researchers to
propose networks based upon optical circuit switches, but these proposals face significant …

With the widespread use of distributed machine learning (DML), many IT companies have
established networks dedicated to DML. Different communication architectures of DML have …

Emerging optical technologies introduce opportunities to recon gure network topologies at
runtime. The resulting topological exibilities can be exploited to design novel demand-aware …

We describe our experience building and deploying a demand-oblivious optically-switched
network based on the RotorNet and Opera architectures. We detail the design, manufacture …

The book gives an in-depth description of key devices of current and next generation fibre
optic communication networks. Devices treated include semiconductor lasers, optical …

With the rapid spread of cloud-based services, intra-datacenter traffic is growing
exponentially. In typical present datacenters, top-of-rack switches, which act as gateways to …

Data centers are continuously growing in scale and can contain more than one million
servers spreading across thousands of racks; requiring a large-scale switching network to …

Highly integrated active nanophotonics addressing both device footprint and operation
speed demands is a key enabling technology for the next generation optical networks …

Wavelength-selective switches (WSSs) are the core devices for reconfigurable optical add-
drop multiplexers (ROADMs) that are essential in all-optical networks. WSSs based on …

Optical circuit switching may be instrumental in meeting the cost, energy, and aggregate
bandwidth requirements of future data center networks. However, conventional MEMS beam …
