abstract = {In photoacoustic and ultrasound imaging, optical transducers 

 offer a unique potential to provide higher responsivity, wider 

 bandwidths, and greatly reduced electrical and acoustic 

 impedance mismatch when compared with piezoelectric transducers. 

 In this paper, we propose a total-internal-reflection-based 

 Fabry-P\'{e}rot resonator composed of a 12-nm-thick gold layer 

 and a dielectric resonant cavity. The resonator uses the same 

 Kretschmann configuration as surface plasmon resonators (SPR). 

 The resonators were analyzed both theoretically and 

 experimentally. The experimental results were compared with 

 those for an SPR for benchmarking. The 1.9-μm-thick-PMMA- 

 and 3.4-μm-thick-PDMS-based resonators demonstrated 

 responsivities of 3.6- and 30-fold improvements compared with 

 the SPR, respectively. The measured bandwidths for the PMMA, 

 PDMS devices are 110 MHz and 75 MHz, respectively. Single-shot 

 sensitivity of 160 Pa is obtained for the PDMS device. The 

 results indicate that, with the proposed resonator in imaging 

 applications, sensitivity and the signal-to-noise ratio can be 

 improved significantly without compromising the bandwidth.},
