[MC2-1]Ultra-Low Loss Hollow Core Fibers: Progress and Outlook
○Francesco Poletti
Over the past two decades, hollow core fibers have emerged as a groundbreaking technology that addresses the inherent limitations of traditional glass core-based telecom fibers. Recent advancements in a novel guidance mechanism, utilizing antiresonances from nested tubes, have significantly accelerated progress. As a result, hollow core technology now boasts the lowest attenuation of any developed waveguide, making it a highly efficient option for data transmission.
This breakthrough has sparked considerable interest within the fiber optics community, prompting collaborations between major industries and academic institutions worldwide. These partnerships aim to tackle various technological challenges, such as improving manufacturing processes, enhancing performance metrics, and ensuring the reliability of hollow core fibers when installed in the field. As research continues, it is essential to identify ongoing challenges, such as scalability and integration with existing infrastructure, to fully realize the potential of hollow core fibers in optical data communications. In this tutorial, we will delve deeper into the latest developments in hollow core fiber technology, explore the challenges that remain, and investigate the future potential for its adoption across various sectors, including telecommunications, data centers, and beyond. By understanding these aspects, we can better appreciate the transformative impact that hollow core fibers may have on the future of optical communication systems.
Bio: Prof Francesco Poletti leads the Hollow Core Fibre (HCF) group at the Optoelectronic Research Centre, University of Southampton. In his research career, he has held a Royal Society Fellowship (URF) and a European Research Council (ERC) consolidator grant, both aimed at advancing the science and technology of hollow core fibres. He has co-authored more than 500 peer-reviewed publications, produced over 20 patents and delivered more than 50 invited, tutorial or keynote presentations. Over the years, he has been an investigator on grants totalling over ~£50M and covering many aspects of fibre fabrication technology. His pioneering work on HCF led to the creation of the ORC startup Lumenisity, which in 2022 was acquired by Microsoft Azure. As a result, he currently also holds a position as a Chief Scientist in Microsoft Azure Fiber, leading the research activities on HCFs for optical data communications.
