We have designed an integrated device that couples input and output coaxial horn antennas with a self-assembled helical slow-wave structure cradled in a v-groove on a silicon-on-insulator wafer. These devices will potentially enable the characterization of cold parameters and beam-wave interaction in slow-wave structures on a wafer level, i.e., without having to dice and package individual devices. In addition, such vertically integrated antennas and helical slow-wave structures may form the basis of compact and low-cost traveling-wave tube amplifiers operating at THz frequencies.
我们设计了一种集成装置，该装置将输入和输出同轴喇叭天线与一个自组装螺旋慢波结构耦合在一起，该慢波结构置于绝缘体上硅晶圆的V形槽中。这些装置有望在晶圆级对慢波结构中的冷参数和束波相互作用进行表征，即无需切割和封装单个器件。此外，这种垂直集成的天线和螺旋慢波结构可能构成太赫兹频率下紧凑型低成本行波管放大器的基础。
