Various types of optical fiber networks have been conceived, designed, and built to satisfy a
wide range of transmission capacities and speeds. The link lengths between users can vary …

The performance of optical devices can degrade because of aging and external causes like,
for example, temperature variations. Such degradation might start with a low impact on the …

The development of digital twins to represent the optical transport network might enable
multiple applications for network operation, including automation and fault management. In …

Optical networks have historically been designed to be operated statically. Connections are
overprovisioned so that they remain uninterrupted over several (eg, 10) years, using high …

Focused on reducing capital expenditures by opening the data plane to multiple vendors
without impacting performance, node disaggregation is attracting the interest of network …

With the growing popularity of 5G mobile communications, cloud and fog computing, 4K
video streaming, etc., population distribution and migration have increasing influence on …

Consistent growth in the volume and dynamic behavior of traffic mandates new
requirements for fast and adaptive resource allocation in metro networks. We propose a …

In this paper, we study the impairment-aware manycast routing, modulation level, and
spectrum assignment problem in elastic optical networks. We formulate a mixed-integer …

Efficient utilization of spectrum is a key concern in the soon to be deployed elastic optical
networks (EONs). To perform routing in EONs, various fixed routing (FR), and fixed-alternate …

By leveraging mode-division multiplexing (MDM), capacity of on-chip photonic interconnects
can be scaled up to an unprecedented level. The demand for dynamic control of mode …
