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. Related Research Topics
