The increasingly higher data rate demands in today’s optical communication networks, such as 260Gbd coherent and 400Gb/s PAM4 systems, drive the need for high bandwidth modulators and receiver photonic integrated chips (PICs), with complex on-chip functionality. The InP material
system offers an extensive and versatile design space that enables the manufacturing of both low Vπ Mach-Zehnder modulators and high responsivity photodiodes capable of reaching 3dB bandwidths in excess of 100GHz. Furthermore, it supports the monolithic integration of diverse photonic components, including, among others, high-gain semiconductor optical amplifiers for signal boosting, spot size converters for low-loss fibre-to-waveguide coupling, low phase error 3/6dB splitters, and variable optical attenuators in conjunction with monitor photodiodes for dynamic real-time signal monitoring and control. Through careful device design and process optimisation these devices can be manufactured with consistently high performance and robust reliability, meeting the stringent requirements of modern optical networks.
PANEL SESSION Wednesday 11:00 - 12:30 UKRI Future Telecoms Research Hubs: recent progress, highlights and future vision UKRI hubs are major national investments which provide significant funding to world-leading UK university research groups and their partners to address research challenges and shape technological developments in critical technologies, including future telecommunications. In early 2024, UKRI and DSIT announced an additional funding boost of £70M to help drive the UK’s efforts to bring forward the next wave of future telecoms technology, including to four major projects led by the universities of Bristol, Cambridge, and Oxford and at Imperial College, London.
Silicon optical modulators for high speed and low power data communication
David Thomson, Silicon Photonics Group, Optoelectronics Research Centre, University of Southampton Our recent progress on silicon optical modulators will be presented, focussing on our work on capacitive modulators where it is shown that strong absorption modulation produced as a side product
of phase modulation can enhance intensity modulation in resonant structures. Our work on the integration of silicon optical modulators and CMOS electronics will also be highlighted showing that by following a co-design approach, the performance of the integrated transmitter can be fully optimised allowing breakthroughs in data throughput and power consumption. Enhancing Photonic Integrated Circuits: Advanced Testing and Automation Strategies Sophie Lange, PhD, Business Development Engineer, EXFO integrated circuits (PIC). Manufacturers and researchers must test growing wafer volumes swiftly without compromising quality. Ensuring accuracy, reliability, traceability, and speed when testing various photonic components requires flexibility, scalability, and a high level of automation and optical performance. As a Test & Measurement solutions provider in the PIC ecosystem, EXFO will present strategies to achieve these goals. These include fully automating motion systems, instrument drivers, and databases from a single interface, as well as creating a reusable and connected test environment from wafer to module. Efficient testing of all components at the wafer level, whether surface- or edge-coupled, is crucial for production environments. Finally, leveraging AI and machine learning will further reduce test time and costs significantly. AI is set to revolutionize the development and mass production of integrated photonic components. The industry now faces the challenge of efficiently testing, assembling, and packaging increasingly complex photonic
