Fiber endface photoacoustic generator for quantitative photoacoustic tomography
Optics Letters, 2021 We demonstrate a novel fiber endface photoacoustic (PA) generator using infrared (IR) 144 laser dye dispersed within an ultraviolet adhesive. The generator provides a wide acoustic bandwidth in the transducer frequency range of 2–7 MHz, high thermal conversion efficiency ( > 90 % ), good PA signal controllability (well ...

Anodically Bonded Photoacoustic Transducer: An Approach towards Wafer-Level Optical Gas Sensors
Sensors, 2022 We present a concept for a wafer-level manufactured photoacoustic transducer, suitable to be used in consumer-grade gas sensors. The transducer consists of an anodically bonded two-layer stack of a blank silicon wafer and an 11 µm membrane, which was wet-
