Integrated switches play a crucial role in the development of reconfigurable optical add-drop
multiplexers (ROADMs) that have greater flexibility and compactness, ultimately leading to …

Increasing traffic in the optical backbone network has made it incumbent upon operators to
extend the use of optical spectrum beyond the C-band. In this work we estimate network …

An artificial neural network (ANN) based transfer learning model is built for quality of
transmission (QoT) prediction in optical systems feasible with different modulation formats …

We investigate cost-efficient upgrade strategies for capacity enhancement in optical
backbone networks enabled by C+ L-band optical line systems. A multi-period strategy for …

We have proposed a dynamically configurable and fast optical impairment model for the
abstraction of the optical physical layer, enabling new capabilities such as indirect …

Routing and wavelength assignment (RWA) algorithms must strike a balance between
finding routes with high quality of transmission (QoT) and finding routes that will not interfere …

Network traffic is growing exponentially, which has increased the onus on network operators
to expand their network spectral resources beyond the C band. This work explores the effect …

The minimization of the number of expensive 3R regenerators required at intermediate
nodes is a key task when planning long-haul optical transport networks. Combining Raman …

We propose a dynamically configurable optical impairment model for a physical layer
abstraction enabling physical parameters learning in multi-vendor networks. We …

Recently, multi-band elastic optical networks (MB-EONs) have been considered a viable
solution to increase the transmission bandwidth in optical networks. To improve spectral …
