Elastic Fabry-Pérot microcavity for high-sensitivity photoacoustic spectroscopy.
We report an elastic Fabry-Pérot microcavity (μFP) acoustic transducer that combines mechanical compliance with resonantly enhanced optical interrogation, boosting the conversion of pressure-induced diaphragm displacement into an optical signal. The transducer comprises a high-reflectivity concave mirror fabricated on...
