本文介绍了一种光控大功率RP脉冲压缩系统的设计和原理验证实验结果。原则上，这种设计应该能在x波段处理几百兆瓦的功率。该系统基于开关谐振延迟线理论。它采用谐振延迟线作为存储射频能量的手段。在充电阶段，对线路的耦合进行了优化，以获得最大的能量存储。为了使线路放电，大功率微波开关在输出脉冲开始前增加与线路的耦合。该系统所需的高功率微波开关是利用纯硅片表面的电子-空穴等离子体层的光激发实现的。该开关设计为在圆波导中以TE/sub 01/模式工作，以避免在硅片和支撑波导之间的接口处存在边缘效应；从而提高其电力处理能力。
We present the design and a proof of principle experimental results of an optically controlled high-power RP pulse-compression system. In principle, the design should handle a few hundreds of megawatts of power at X-band. The system is based on the switched resonant delay-line theory [1]. It employs resonant delay lines as a means of storing RF energy. The coupling to the lines is optimized for maximum energy storage during the charging phase. To discharge the lines, a high-power microwave switch increases the coupling to the lines just before the start of the output pulse. The high-power microwave switch required for this system is realized using optical excitation of an electron-hole plasma layer on the surface of a pure silicon wafer. The switch is designed to operate in the TE/sub 01/ mode in a circular waveguide to avoid the edge effects present at the interface between the silicon wafer and the supporting waveguide; thus, enhancing its power handling capability.
