RT Journal Article T1 Selectivity of SPR fiber sensors in absorptive media: An experimental evaluation A1 Navarrete Fernández, María Cruz A1 Díaz Herrera, Natalia A1 González Cano, Agustín A1 Esteban Martínez, Óscar A1 Leite, Ivo AB Conventional surface plasmon resonance (SPR) fiber sensors show selective behavior when resonance wavelengths are tuned to absorption peaks of the surrounding medium, as it is experimentally shown and evaluated in this paper by using a doubly-deposited uniform-waist tapered optical fiber (DLUWT) and a dye as a test material. This behavior is clearly distinguishable from the usual response to nonabsorbing media and can be used to develop a new concept of SPR transducers. At the same time, the obtained results, which are in accordance with the theoretical predictions permit to increase the basic knowledge on surface plasma waves excitation in optical fibers.
