    Metadata Updated: September 30, 2023

    'Beating thermal noise in a dynamic signal measurement by a nanofabricated cavity-optomechanical sensor', Mingkang Wang, Diego J. Perez-Morelo, Georg Ramer, Georges Pavlidis, Jeffrey J. Schwartz, Liya Yu, Robert Ilic, Andrea Centrone, and Vladimir A. Aksyuk, Science Advances 9, eadf759, 2023.DOI:10.1126/sciadv.adf7595Thermal fluctuations often impose both fundamental and practical measurement limits on high-performance sensors, motivating the development of techniques that bypass the limitations imposed by thermal noise outside cryogenic environments. Here, we theoretically propose and experimentally demonstrate a measurement method that reduces the effective transducer temperature and improves the measurement precision of a dynamic impulse response signal. Thermal noise limited, integrated cavity-optomechanical atomic force microscopy probes are used in a photothermal induced resonance measurement to demonstrate an effective temperature reduction by a factor of ? 25; i.e., from room temperature down as low as ? 12 K, without cryogens. The method improves the experimental measurement precision and throughput by > 2x, approaching the theoretical limit of ? 3.5x improvement for our experimental conditions. The general applicability of this method to dynamic measurements leveraging thermal-noise-limited harmonic transducers will have a broad impact across a variety of measurement platforms and scientific fields.
