我们报告了一种基于电光机械转换方案的射频-光转换器，其中电、光和机械接口集成在芯片上，并使用光纤耦合光学设置进行操作。该设备专为磁共振扫描仪的现场测试而设计，其小尺寸和简单的操作至关重要。对于32 MHz的附属磁共振检测电路，我们演示了具有8 fT/Hz的固有磁场灵敏度、噪声系数2.3 dB、噪声温度210 K、电压噪声99 pV/Hz和电流噪声113 pA/Hz的转导，所有这些都在12 kHz的3 dB带宽内。这样的灵敏度和带宽使传感器成为传统电子前置放大器的有价值的替代品，该电子前置放大器另外与光纤通信网络直接兼容。
We report a radio-frequency-to-optical converter based on an electro-optomechanical transduction scheme where the electrical, optical, and mechanical interface was integrated on a chip and operated with a fiber-coupled optical setup. The device was designed for field tests in a magnetic resonance scanner where its small form-factor and simple operation is paramount. For the appurtenant magnetic resonance detection circuit at 32 MHz, we demonstrate transduction with an intrinsic magnetic field sensitivity of 8 fT/Hz, noise figure 2.3 dB, noise temperature 210 K, voltage noise 99 pV/Hz, and current noise 113 pA/Hz, all in a 3 dB-bandwidth of 12 kHz. Such sensitivity and bandwidth make the transducer a valuable alternative to conventional electronic preamplifiers that additionally is directly compatible with fiber communication networks.
