随着微波光子技术的发展, 在解决传统射频领域无法直接实现的功能方面已经有了很大的成就, 同时大大促进了光电子通信技术的发展。然而, 微波光子技术仍面临着新的挑战: 现有的光通信系统由分立的光/电、电/光等元器件构成, 在不断追求更高速率、更大带宽和更强处理能力的通信系统的现状下, 要求器件和系统的尺寸更小、功耗更低及抗干扰能力更强。因此, 通过硅基集成技术和微波光子技术的结合实现微波光子学系统芯片集成化, 从而降低整个系统的成本、缩小尺寸、降低功耗, 是微波光子学发展的必然趋势。文章总结了微波光子集成技术和硅基光子器件的发展现状, 指出可调谐、可编程的硅基微波光子芯片必将成为**领域和民用方面发展的关键技术。

With the development of microwave photonics technology, great achievements have been achieved in solving the function that cannot be directly realized in the traditional RF field, and the development of optoelectronic communication technology is greatly promoted. However, microwave photon technology is still facing new challenges: the existing optical communication system consists of discrete optical/electrical, electrical/optical components, smaller size of devices and systems in the constant pursuit of higher speed, higher bandwidth, higher processing power of communication systems, lower power consumption and stronger anti-interference ability. Therefore, by silicon integrated technology and microwave photonic technology combined with microwave photonics system chip integration, thus reducing the cost, smaller size, lower power consumption of the whole system, is the inevitable developing trend of microwave photonics. This paper summarizes the development of microwave photonic integrated technology and silicon-based photonic devices. It is pointed out that tunable and programmable silicon-based microwave photonic chips will become the key technology to limit the development of military and civilian fields.
