Abstract:
Hyperbolic metamaterials (HMMs) have attracted significant attention with regards to applications related to surface plasmon resonance (SPR) because of their heterodyne response induced by the multimode response and the high K-transfer mode (including transmission and dielectric ones) originated from their unique dispersive properties. However, most HMM-based applications related to fiber optic SPR are still at the theoretical simulation stages. This work reports the synthesis of HMMs using Ag and MgF 2 . The resulting HMMs were used to fabricate an SPR sensor based on D-type plastic optic fibers (D-POFs). The sensor oscillation modes were theoretically analyzed using the effective medium theory and COMSOL. The optimal synthesis conditions were when the metal filling fraction ( ρ ) and the number of bilayers ( N bi ) were equal to 0.5 and 3, respectively. Experiments showed that at the ambient refractive index in the 1.34–1.356 RIU range, the HMMs/D-POF sensor possessed high sensitivity (1875 nm per RIU), excellent linear response (with the correlation coefficient R 2 = 0.987), and reproducibility. Our sensor could also detect saccharin and 2, 6-di- tert -butyl-4-methyl phenol antioxidant 264 (BHT), both of which are toxic. Thus, both theoretical and experimental results showed the applicability of this sensor for real-life detection.
