Planar waveguides with ultra‐low optical propagation loss enable a plethora of passive
photonic integrated circuits, such as splitters and combiners, filters, delay lines, and …

In the evolution of optical networks, spectral efficiency (SE) enhancement has been the most
cost-efficient and thus the main driver for capacity increase for decades. As a result, the …

Networking technologies are fast evolving to support the request for ubiquitous Internet
access that is becoming a fundamental need for the modern and inclusive society, with a …

Optical fibres have for almost three decades been fabricated of solid glass. It was, therefore,
a radical change that took place, when researchers in the late 90's started to fabricate hair …

The presence of bound hydroxyl (SiOH) in silica is well known to produce an optical
fundamental absorption band at about 2.7 μm. For optical fiber applications the influence of …

This paper has clarified the conventional silica doped (SiGeO2) and aluminum fluoride
(AlF3) fibers for low loss and minimum dispersion effects for upgrading fiber-optic …

We investigate quality of transmission (QoT) estimation in a multi-band transmission
scenario, including a wideband description of the frequency-dependent physical layer …

In the direction of disaggregated and cognitive optical networks, this work proposes and
experimentally tests a vendor-agnostic optical line controller architecture capable of …

Over the past decades, optical technologies have entered neural implant technologies.
Applications such as optogenetics, near-infrared spectroscopy (NIRS), and direct-near …

Increasing traffic demands are causing network operators to adopt disaggregated and open
networking solutions to better exploit optical transmission capacity, and consequently …
