摘要
可编程微波光子芯片是可以通过编程控制改变芯片功能,用于处理微波信号的光子芯片。它可以在同一芯片上软件定义不同的光学处理单元,以实现滤波、移相、延时等多种信号处理功能。相比于只能实现特定功能的专用微波光子芯片,可编程微波光子芯片功能可重构,可广泛应用于通信、雷达等光电子系统中,提升系统灵活性。本文对可编程微波光子芯片的研究现状进行了梳理,介绍了其光路拓扑、主要实验结果和关键技术并对可能的发展方向进行了总结。
Programmable microwave photonic chips are photonic chips which are used to process microwave signal and can be programmed to achieve different functions.Different optical units can be software-defined on a single chip to realize multiple signal processing functions,such as filtering,phase shifting and time delay.Compared with application specific microwave photonic chips,they have strong advantage in reconfigurability and can be widely used in communication and radar system to improve the flexibility and versatility of the system.Research Status of programmable microwave photonic chips is reviewed,and their topological structure,main experimental results and key technology are introduced.At last,the future trends are summarized.
