Dual-environment Pressure Sensor Using A Photonic-crystal Fiber

In this paper, we report the development of a side-hole photonic-crystal fiber (SH-PCF) based dual-environment pressure sensor. SH-PCF sensitivity to pressure variations was measured and compared to simulated data. SH-PCF sensitivity was found to be 2.8 times higher than the one presented by the commercial PM-1550-01 fiber. For probing two environments, one spliced two sections of the studied SH-PCF with different lengths in a solc-filter-like configuration. Individual responses of the first and second fiber can be independently obtained in this setup. Therefore, making use of SH-PCF sensitivity to pressure variations, a pressure sensor for dual environment monitoring is build up. © 2014 SPIE.9157BaySpec,COPSESA,et al.,FiberCore,FiberSensing,OZ OpticsRussel, P., Photonic crystal fibers (2003) Science, 299 (5605), pp. 358-382Statkiewicz, G., Martynkien, T., Urbanczyk, W., Measurements of modal birefringence and polarimetric sensitivity of the birefringent holey fiber to hydrostatic pressure and strain (2004) Optics Communications, 241 (4-6), pp. 339-348Dong, X., Tam, H.Y., Shum, P., Temperature-insensitive strain sensor with polarization-maintaining photonic crystal fiber based Sagnac interferometer (2007) Applied Physics Letters, 90, pp. 151113-1511133Martins, H., Marques, M.B., Jorge, P., Cordeiro, C.M.B., Frazão, O., Intensity curvature sensor based on photonic crystal fiber with three coupled cores (2012) Optics Communications, 285, pp. 5128-5131Szpulak, M., Martynkien, T., Urbanczyk, W., Effects of hydrostatic pressure on phase and group modal birefringence in microstructurated holey fibers (2004) Applied Optics, 43, pp. 4739-4744Fávero, F.C., Quintero, S.M.M., Martelli, C., Braga, A.M.B., Silva, V.V., Carvalho, I.C.S., Llerena, R.W.A., Valente, L.C.G., Hydrostatic pressure sensing with high birefringence photonic crystal fibers (2010) Sensors, 10, pp. 9698-9711Nasilowski, T., Martynkien, T., Statkiewicz, G., Szpulak, M., Olszewski, J., Golojuch, G., Urbanczyk, W., Thienpont, H., Temperature and pressure sensitivities of the highly birefringent photonic crystal fiber with core asymmetry (2005) Applied Physics B, 81, pp. 325-331Jewart, C.M., Quintero, S.M., Braga, A.M.B., Chen, K.P., Design of a highly-birefringent microstructured photonic crystal fiber for pressure monitoring (2010) Optics Express, 18 (25)Osório, J.H., Cordeiro, C.M.B., Optical sensor based on two in-series birefringent optical fibers (2013) Applied Optics, 52, pp. 4915-492
