Abstract
Photonics integrated circuits support an immense signal bandwidth with very linear behavior and low losses, making them ideal for analog signal processing in (fiber-based) distributed systems. Both optical and microwave signals (encoded on an optical carrier) can be filtered, equalized, shifted in frequency, and converted between domains. By chaining these different functions together in larger circuits with configurable connectivity, and making every element tunable, it becomes possible to create multi-functional analog signal processors. We will present our recent results in realizing such programmable photonic systems, which combine lasers, modulators, filters and detectors on a single chip, and interface them with the necessary driver and control electronics. We will also discuss the key challenges to scale such systems, including algorithms and software, and how they can redefine how developers and researchers use photonic chips.

Wim Bogaerts is a professor in the Photonics Research Group at Ghent University and the IMEC nanotechnology research center in Belgium. He completed his PhD in 2004, pioneering the use of industrial CMOS fabrication tools to build photonic circuits. Between 2000 and 2010, he was the driver behind the buildup of IMEC’s silicon photonics technology. In parallel, he started developing design automation tools to implement complex silicon photonic circuits. In 2014, he co-founded Luceda Photonics, bringing the design tool IPKISS to the market. In 2016 he won a research grant from the European Research Council, and since then he is again full-time at Ghent University – IMEC, focusing on the challenges for large-scale photonic circuits and the new field of programmable photonics. He is an IEEE and OPTICA Fellow, and senior member of SPIE.
