Abstract

Low-loss transmission and sensitive recovery of weak radio-frequency (rf) and mi- crowave signals is an ubiquitous technological challenge, crucial in fields as diverse as radio astronomy, medical imaging, navigation and communication, including those of quantum states. Efficient upconversion of rf-signals to an optical carrier would al- low transmitting them via optical fibers instead of copper wires dramatically reducing losses, and give access to the mature toolbox of quantum optical techniques, routinely enabling quantum-limited signal detection. Research in the field of cavity optomechan- ics [1, 2] has shown that nanomechanical oscillators can couple very strongly to either microwave [3–5] or optical fields [6, 7]. An oscillator accommodating both these func- tionalities would bear great promise as the intermediate platform in a radio-to-optical transduction cascade. Here, we demonstrate such an opto-electro-mechanical trans- ducer following a recent proposal [8] utilizing a high-Q nanomembrane. A moderate voltage bias (Vdc
