集成天线调制器的单体光子射频接收机
摘要
集成射频(RF)光子学在无线通信、传感和雷达方面因其大的固有带宽、远距离分布能力和紧凑的占地面积而起着关键作用。然而，尽管PIC(光子集成电路)方面取得了显著进展，但实际部署仍受限于essential RF组件(如笨重的天线、放大器和电缆)的笨重特性，尤其是在秘密、柔性和受限空间的应用中。为克服这些限制，单体电子-光子集成电路(EPIC)正受到广泛关注。作为突破性进展，我们展示了一种 novel photonic RF receiver that monolithically integrates a bow-tie antenna and a microring modulator on a thin-film lithium niobate platform. The chip innovatively leverages dual-resonance enhancement mechanism, RF resonance from the antenna and optical resonance from the microring, to significantly boost the RF-to-optical conversion efficiency. A record-high figure of merit (FOM) of 3.88 W-1/2 is achieved within a compact footprint of 2*1.7 mm2. As the first demonstrations, the integrated receiver is deployed in an integrated sensing and communication (ISAC) system, achieving centimeter-level radar ranging accuracy and 3.2 Gbps wireless communication capacity, as well as real-time video transmission function in moving scenarios. This seminal work paves a new way for covert, conformal, and miniaturized frontends in wireless communication and sensing applications, including body area networks, unmanned aerial vehicles, high-speed vacuum maglevs, and electronic warfare systems.
