微波光子集成及前沿展望（特邀）

微波光子学是一门融合了微波技术和光子技术的交叉学科，是研究光波和微波在媒质中的相互作用以及在光频域实现微波信号的产生、处理、传输及接收的微波光波融合系统。由于现有的微波光子系统大多由分立器件组成，在体积、功耗、稳定性、成本等方面仍有待提升，因此集成化是微波光子技术发展的必然趋势。文中探讨了微波光子集成技术面临的主要科学与技术问题，总结了该技术的发展现状和前沿研究进展，并对其未来发展前景进行了展望。

Frontiers and prospects of integrated microwave photonics (Invited)

Microwave photonics is an interdisciplinary subject of microwave engineering and photonics technology. It is a fused microwave and optical system that studies the interaction between optical and microwave signals in the medium and the generation, processing, transmission, and receiving of microwave signals in the optical domain. Integration is an inevitable trend of microwave photonics since the performances of current discrete devices-based microwave photonic systems are poor in terms of size, power consumption, stability and cost. The main scientific and technical issues of integrated microwave photonics were discussed, its development status and frontier research progresses were summarized, and an outlook of its future prospects was given.
