Very Small Fibre Optic Interconnect Solutions Supporting the Exponential Bandwidth Demand
Philip Ward, SENKO Advanced Components Not only because of the data traffic bandwidth increase but also with the adoption of artificial intelligence and machine learning, the use and demand of fibre optics in data centres is increasing exponentially. . In this presentation, Tiger Ninomiya will provide a density and size study addressing

fibre optic connectivity options, very mallsmall form factor (VSFF) connectors to increase the density of the footprint at the pluggable transceiver level, and the faceplate design of co-packaged optics and metallic PIC connector to achieve a compact package design for the fibre-to-chip coupling in CPO applications where size constraints are paramount to meet and exceed emerging technology barriers.
Pump Lasers for Optical Amplification in Telecommunication Network Design, Reliability and Applications Nadhum Zayer, Coherent
Optical communication networks have been enabled by the development of the in-fibre optical amplifier. There are many ways of generating signal amplification within the optical fibre network such as using doped fibre amplifiers (erbium for example) or Raman effect

amplification. Pump lasers are a fundamental part of in-fibre optical amplifier designs. This invited talk covers design, development, reliability, and manufacturing of pump lasers required for in-fibre amplifiers. The application and the requirements for the pump lasers in terrestrial, under-sea and space deployments are discussed and compared. Components for – and system demonstrations using spatial division multiplexing Georg Rademacher, University of Stuttgart Space-division multiplexing (SDM) offers a fibers, including multi-mode and multi-core fibers. Each SDM fiber requires a specific eco-system of devices and algorithms to harvest the full potential that each technology offers, including spatial multiplexers, optical fibers but also receivers and digital signal processors to undo coupling between spatial paths, introduced during transmission. Recently, SDM fibers that conform with the current industry standard for the cladding diameter of 125 µm have been intensively investigated. To reach peta-bit/s transmission in standard-cladding diameter fibers, strongly-coupled spatial channels, such as in randomly coupled multi-core fibers or multi-mode fibers are needed. In this talk, we will review key components and technologies required to implement SDM transmission in multi-mode and multi-core fibers. tremendous potential for high speed optical fiber communications systems by leveraging parallel transmission paths in optical fibers to transmit independent data signals. SDM transmission has been demonstrated using various kinds of optical
Noise-robust transport and manipulation of photonic spatial mode entanglement
Mehul Malik, Heriot-Watt University Quantum states of light entangled in high dimensions offer the potential for noise-robust quantum communication networks that harness the full information carrying capacity of a photon. A central challenge in the realisation of such networks is the ability to precisely control
and reliably transport high-dimensional entangled states of light. In this talk, I will discuss the generation of high-dimensional “pixel” entanglement with fidelities exceeding 94% and entanglement dimensionalities up to 55. I will then present an experiment on the transport of entanglement through extreme regimes of noise and loss corresponding to 79km of optical fibre. Finally, I will discuss the manipulation of high-dimensional quantum states of light achieved via the inverse-design of programmable quantum circuits inside a commercial multi-mode fibre.
Toward Wide-Field-of-View and Large Area Optical Detectors for High-Speed Optical Wireless Communication
How Does Optical Networking Fit in Telecoms Network Architecture
Andy Reid, Smart Internet Lab, University of Bristol
Abderrahmen Trichili, University of Oxford Optical wireless communication (OWC) is able to provide high-throughput connectivity for 6G networks and beyond. A major limiting factor of the wide-scale deployment of OWC is the limited field of view (FoV) and small active areas of high- speed receivers, which derives strict pointing,
The opportunity for transparent optical networking (whether based on networked WDM, some form of optical burst solution, or a mixture of the two) is squeezed by the low cost of additional by-pass fibre strands below and
the low cost of electronic packet switching above. For many network planners, this issue is not always helped by academic work which tends to oversimply network scenarios which means it is hard to translate academic results into realistic network solutions. This presentation sets out an analysis and optimisation framework which takes into consideration sufficient of the real-world constraints faced by network planners to give realistic and implementable solutions and is general such that it can represent a wide variety of operators’ networks. Using this framework, the presentation then reports on the opportunity for optical networking with the technical and commercial parameters which would make optical switching technology attractive to network planners.
acquisition, and tracking (PAT) requirements. This talk highlights the potential of designing large-area detectors with extended FoVs to ease PAT requirements for OWC systems.
