Numerical And Experimental Studies For A High Pressure Photonic Crystal Fiber Based Sensor

We report a study of using photonic crystal fibers (PCFs) for high pressure applications. An opto-mechanical analysis was realized in regular PCFs and suspended-core microstructured optical fibers for different fiber geometrical parameters. It was found that the pressure sensitivity is highly dependent on the fiber structure. It was also experimentally shown that even small core PCFs with high air filling fraction can deal with pressures as high as 500 bar (7350 psi) without any noticeable problem. © American Institute of Physics.1055133136de Matos, C.J.S., (2008) CLEO conferenceR.E.P. de Oliveira, submitted to WSOF2008 AIP Proceedings (2008)Cordeiro, C.M.B., (2007) Optics Letters, 32, pp. 3324-3326Szpulak, M., Martynkien, T., Urbanczyk, W., (2004) Appl.
