摘要

我们设计并演示了一种适用于复杂多波束相控阵天线接收系统的DC-18 GHz GaAs行波调制器。该设计的定义特征是片上光路折叠，以实现所需的Rx模块的密集封装，一端是RF输入，另一端是光学询问。芯片损耗低于6db。光学S/sub /较低，主要受光学面ar涂层的影响。

A folded-path GaAs travelling-wave modulator for phased array receivers

We have designed and demonstrated a DC-18 GHz GaAs travelling-wave modulator suitable for a complex multi-beam phased-array antenna receive system. The defining feature of the design is on-chip optical path-folding to enable the needed dense packing of the Rx modules with RF input at one end and optical interrogation from the other. Chip loss is below 6 dB. The optical S/sub 11/ is low and dominated by the AR-coating of the optical facet.
