Issue Date: | 2017 | Journal: | ACS Omega | Abstract: | We propose a highly sensitive sensor based on enhancing the transversal magneto-optical Kerr effect (TMOKE) through excitation of surface plasmon resonances in a novel and simple architecture, which consists of a metal grating on a metal magneto-optical layer. Detection of the change in the refractive index of the analyte medium is made by monitoring the angular shift of the Fano-like resonances associated with TMOKE. A higher resolution is obtained with this technique than with reflectance curves. The key aspect of the novel architecture is to achieve excitation of surface plasmon resonances mainly localized at the sensing layer, where interaction with the analyte occurs. This led to a high sensitivity, S = 190 degrees RIU-1, and high performance with a figure of merit of the order of 10(3), which can be exploited in sensors and biosensors. | URI: | http://hdl.handle.net/10553/35452 | ISSN: | 2470-1343 | DOI: | 10.1021/acsomega.7b01458 | Source: | ACS Omega [ISSN 2470-1343], v. 2 (11), p. 7682-7685 |
