We propose a novel co-packaged optical transceiver architecture capable of operating at 112 Gbaud per lane and scalable to 1.6 Tb/s capacity and beyond for next generation 51.2T and 102.4T digital switches.

We propose a novel approach to mitigate the limitations of high-speed Passive Optical Networks (PONs) by introducing an all-optical processor. This solution addresses the escalating demand for higher data rates and improved performance in future access networks. The all-optical processor leverages optical signal processing to enhance system efficiency and reduce power consumption compared to traditional electrical methods. Specifically, we explore the processor’s dual functionality in performing all-optical equalization and chromatic dispersion compensation. Our research includes a comprehensive analysis of the processor’s design, operational principles, and system validation through extensive simulation studies, demonstrating significant improvements in signal quality and overall network performance. The results indicate that the all-optical processor not only relaxes the DSP and power requirements but also outperforms the more sophisticated digital counterpart methods.

The transformation of datacentres to support the increasing traffic growth requires the development of new technologies to migrate to 1.6T optical transceivers and to ultra-fast high radix optical space switches. In this work, an outline of the technological perspectives of TWILIGHT project is provided in accordance with research updates and industry standards.

The immense growth of data traffic that traverses modern networks, calls for immediate solutions to tackle the challenges that arise in terms of speed, capacity, cost and energy efficiency. This manuscript outlines the key technological aspects of the PICaboo project, that aims to develop novel building blocks and photonic integrated circuits for the next generation of optical metro and access networks enhanced with optical signal processing functionalities exploiting the generic foundry model approach.

As new technologies emerge, more and more people depend on them for a variety of purposes. Now more than ever there is a tendency for technological implications to substitute for face-to-face communication and education. In this paper we attempt to investigate whether the usability and pedagogical factors for quality educational platforms meet the expectations of three dominant learning theories of the past century, which, namely are: behaviorism, cognitivism and constructivism. We assign specific factors derived from 9 evaluation models to the 3 learning theories. A list of 15 questions was produced to help evaluators in the assessment of the educational software. Then we evaluated 11 educational websites that aim to help anglophone students improve their language skills e.g. through grammar and spelling exercises. The results show the level of correspondence of these educational websites to the learning theories.

We propose an optical pre-equalizer which relaxes the need for power-hungry DSP in IM/DD applications. A reservoir computing-based approach is pursued demonstrating under FEC performance up to 6km at 50Gbaud NRZ outperforming digital FFE.
