Based on the concept of infrastructure as a service, optical network virtualization can
facilitate the sharing of physical infrastructure among different users and applications. In this …

We are witnessing the evolution of optical networks toward highly heterogeneous, flexible
networks with a widening area of application. As the bandwidth and reliability performance …

Abstract Space division multiplexing (SDM) is a promising optical network solution with the
scaling potential to overcome the possible capacity crunch problem in backbone networks …

As traffic volumes carried by optical networks continue to grow by tens of percent year over
year, we are rapidly approaching the capacity limit of the conventional communication band …

To support the development of intelligent optical networks, accurate modeling of the physical
layer is crucial. Digital twin (DT) modeling, which relies on continuous learning with real-time …

Rigid fixed-grid wavelength division multiplexing (WDM) optical networks can no longer
keep up with the emerging bandwidth-hungry and highly dynamic services in an efficient …

In this paper, we discuss building blocks that enable the exploitation of optical capacities
beyond 100 Gb/s. Optical networks will benefit from more flexibility and agility in their …

This paper investigates the spectrum fragmentation issue, which undermines the bandwidth
efficiency in elastic optical networks. After categorizing the two-dimensional fragmentation …

In recent years, OFDM has been the focus of extensive research efforts in optical
transmission and networking, initially as a means to overcome physical impairments in …

Since the discovery of the Bragg's law in 1913, Bragg gratings have become important
optical devices and have been extensively used in various systems. In particular, the …
