According to Web of Science (https://en.wikipedia.org/wiki/Web_of_Science) Essential Science Indicators (https://clarivate.com/products/essential-science-indicators/), and based on the most recent data released, this paper has received enough citations now to place it in the top-1% of its academic field (ECE) based on a highly cited threshold for the field and the publication year (considering all publications that year from all over the world).

The paper is entitled: “Survey of Photonic Switching Architectures and Technologies in Support of Spatially and Spectrally Flexible Optical Networking” and was published at the January 2017 issue of the “Journal of Optical Communications and Networking” (DOI10.1364/JOCN.9.000001). It was co-authored by well-known researchers (Dan M. Marom, Paul D. Colbourne, Antonio D’Errico, Nicolas K. Fontaine, YuichiroIkuma, Roberto Proietti, Liangjia Zong, José M. Rivas-Moscoso, and Ioannis Tomkos) from top academic institutions and companies (Hebrew University of Jerusalem, Lumentum, Ericsson, Nokia Bell Labs, NTT, University of California, Huawei and AIT) based across the world.

The article discussed the photonic switching hardware solutions in support of evolving optical networking solutions enabling capacity expansion based on the utilization of network bandwidth elasticity in the spectral and spatial domain.
It focuses on new wavelength-selective switch designs that can now support greater resolution and increased functionality, as well as greater throughput’s.
System trade offs between switching granularity versus implementation complexity and cost, for such novel optical communication technologies supporting Spatially-Spectrally Flexible Optical Networks (SS-FONs) have been also discussed therein for the first time.
