Resumen
Fiber optic structures based on multimode interference were investigated to the refractive index (RI) sensing. The proposed device is a singlemode-multimode-singlemode (SMS) structure, where the multimode section is a coreless fiber (MMF). The numerical analyses were carried out by beam propagation and modal expansion methods. Ultra-high sensitivity was obtained: 827 nm/RIU over a RI range of 1.30-1.44 and a maximum sensitivity of 3500 nm/RIU for RI∼1.43, considering △RI = 0.01. The dependence of spectral bandwidth was investigated taking into account the multimode fiber diameter and the coupling efficiency between modes at the input junction singlemode- multimode. © 2012 SPIE. 8421
