Abstract

This letter reports a photothermal transducer consisting of an ultrathin AuSi bimetal cantilever that functions as a resonator having a total thickness of 45 nm and a quality factor of ∼12 000. Due to its high-quality factor and small volume, this transducer is sensitive to the photothermal effect and its thermal response frequency is comparatively high. The authors demonstrated that the irradiation of a weak laser beam can enhance the transducer's response due to the nonlinear photothermal effect. Mechanical frequency-modulated detection of modulated light is demonstrated using this bimetal transducer.
