Flexibility to support mesh topologies, dynamic capacity allocation, and automated network
control and light path setup are key elements in the design of next-generation optical …

Elastic optical networking (EON) with space-division multiplexing (SDM) is the only evident
long-term solution to the capacity needs of the future networks. The introduction of space via …

Recent advances in optical communications not only increase the capacities of
communication system but also improve the system dynamicity and survivability. Various …

A large number of factors generate uncertainty on traffic demands and requirements. In
order to deal with uncertainty optical nodes and networks are equipped with flexibility. In this …

A compact silicon photonic wavelength-selective switch (WSS) based on an array of
elliptical microrings with adiabatically varied radii and widths is proposed and demonstrated …

We present the Architecture on Demand (AoD) concept whereby transparent optical cross-
connects (OXC) do not have an associated static architecture but can adapt their …

We propose a novel method to assess physical layer potentialities of core optical networks
aimed at finding solutions that better exploit the installed equipment. We focus on the use of …

Wavelength-selective switches (WSS) have large potential applications in future high-
capacity, low-latency, flexible, and energy-efficient data center optical networks. Here, a …

In this paper, we study the performance of dynamic routing and wavelength assignment
(RWA) in filterless optical networks. These types of broadcast and select networks benefit …

A wavelength selective switch (WSS) can route optical signals into any of output ports by
wavelength, and is a key component of the reconfigurable optical add/drop multiplexer. We …
