This paper demonstrates a passive, integrated electro-optic receiver for detection of free-space microwave radiation. Unlike a traditional microwave receiver, which relies on conductive antennas and electrical amplifiers, this receiver uses only passive, optically probed elements with no electrodes or electronic components. The receiver employs two co-resonant structures: a dielectric resonator antenna (DRA) to concentrate incoming microwave radiation and an integrated aluminum nitride (AlN) racetrack resonator to resonantly enhance the optical carrier. The microwave field of the DRA modulates the built-up optical carrier in the resonator via the electro-optic response of AlN. We successfully detected 15 GHz microwave radiation through co-resonant electro-optic up-conversion, without the need for any conducting electrodes, amplifiers, or electronic components.

氮化铝双谐振无金属电光微波接收器


本文展示了一种用于检测自由空间微波辐射的无源集成电光接收器。与依赖导电天线和电放大器的传统微波接收器不同，该接收器仅使用无源光学探测元件，没有电极或电子元件。该接收器采用两种共谐振结构：用于集中传入微波辐射的介电谐振器天线 (DRA) 和用于谐振增强光学载波的集成氮化铝 (AlN) 跑道谐振器。 DRA 的微波场通过 AlN 的电光响应来调制谐振器中的内置光学载波。我们通过共谐振电光上变频成功检测到 15 GHz 微波辐射，无需任何导电电极、放大器或电子元件。
