Abstract

A new structure of optically-controlled microwave switches is studied. By analyzing the equivalent schematic representation, the ON/OFF ratio of photoswitching systems is enhanced. A 15.4 dB ON/OFF ratio at a microwave frequency of 20 GHz was measured on Si samples with this new configuration, top-excited by a continuous laser diode at a 671 nm wavelength. Such efficient devices can be directly incorporated in passive and active microwave circuits to be switched with the advantages of optics.

半导体基板上的一种新型光控微波开关，用于提高开/关比

研究了一种新型光控微波开关结构。通过分析等效原理图，提高了光电开关系统的开/关比。在微波频率为20 GHz的情况下，用连续激光二极管在671 nm波长处进行顶激发，在这种新结构的Si样品上测量了15.4 dB的开/关比。这种高效的器件可以直接集成在无源和有源微波电路中，利用光学的优势进行切换。
