A numerical model of Gaussian beam propagation in planar Fabry-Perot (FP) etalons is presented. The model is based on the ABCD transfer matrix method. This method is easy to use and interpret, and readily connects models of lenses, mirrors, fibres an

[EN] Porous materials have demonstrated to be ideal candidates for the creation of optical sensors with very high sensitivities. This is due both to the possibility of infiltrating the target substances into them and to their notable surfaceto-volume

An optical sensor based on a self-standing porous silicon (PS) membrane is presented. The sensor was created by electrochemically etching a heavily doped p-type silicon wafer with an organic electrolyte that contained dimethylformamide. After fabrica

Photons Plus Ultrasound: Imaging and Sensing 2021.
The impact of optical absorption in the spacer layer of Fabry-Perot (FP) ultrasound sensors is discussed. It is shown that absorption significantly limits the sensitivity of planoconcave microresonators (PCMRs; FP type sensors with a planoconcave geo

Deep tissue applications (>1 cm) for photoacoustic imaging are currently limited for traditional Fabry-Perot ultrasound transducers interrogated by tightly focused Gaussian beams due to beam walk-off. We investigate the optical confinement of the bea

Fabry-Perot (FP) polymer film sensors are used as ultrasound sensors for Photoacoustic (PA) imaging. Optical models predict that FP sensors should have higher sensitivity than observed experimentally. The models assume FP sensors to be optically flat

Porous silicon (PS) is a good host for fabricating high sensitivity sensors due to the high aspect ratio between surface and volume that can be achieved. The anodization in hydrofluoric acid solutions forms nano-size pores with a few microns of thick
