EPFL researchers have developed a theoretical method that uses optomechanics to amplify weak signals. Signal amplification is one of the most common needs in research and technology. But this requires fine-tuning the amount of noise allowed in order to avoid obscuring the actual. Weak force amplification describes the process of amplifying a faint low-frequency signal by means of an additional high-frequency modulation, which plays a vital role in quantum sensing and high-precision measurement. The demonstrated device exhibits considerable flexibility and offers. Booster (power) amplifiers: Boost power into transmission fiber, low NF, high Psat. An applied drift voltage effectively creates a...
