Silicon photonic integrated circuits for microwave signal generation and processing

摘要

High-frequency microwave signal generation and processing are highly needed in future multi-functional radar and nextgenerationwireless communication systems. It is extremely difficult or impossible for electronics to fulfil the tasks. Asan enabling technology, photonics has been considered a promising solution for the generation and processing of highfrequencymicrowave signals. In this paper, photonic integrated solutions for microwave signal generation andprocessing will be discussed. Specifically, a monolithically integrated silicon-photonic frequency-tunable microwavebandpass filter and a frequency-tunable low phase-noise optoelectronic oscillator are discussed. This successfuldemonstration of the two integrated microwave photonic systems marks a significant step forward for large-scaleimplementation of integrated microwave photonic systems for future radar and wireless communication applications.
