In particular, the way to improve sensitivity is utilization of the magneto-optical multilayer in structure to measure a magneto-optical (MO) response instead of the amplitude of transmitted or reflected wave [2].</p><br /><p>In the present work, we demonstrate 500-mm-sized slabs of plasmonic 1D nanostructures for detecting low density lipoproteins (LDL): sample <strong>A</strong>鈥揹ielectric nanoridges coated with 40-nm-thick Au and sample <strong>B</strong> is a similar one based on bismuth-substituted yttrium iron garnet (Bi:YIG). We experimentally and theoretically studied their optical spectra, gave an explanation on resonant light coupling and optimized designs of the structures. For these designs, we measured and numerically analyzed optical and magneto-optical (MO) responses in the transmission geometries when modeling biomolecular binding for LDL detection with a low concentration. Numerical models of sample <strong>A</strong> and <strong>B</strong> were set up for one unit cell of the 1D grating; experiment and calculations聽were carried out for the <strong>E<em><sub>x</sub></em></strong>-polarized light (see Fig.1).</p><br /><p>We have found that, by introducing Bi:YIG layer, the sensitivity can be significantly enhanced when measuring the MO response in the vicinity of the Fano peak. Indeed, a change in the angle of Faraday rotation 螖胃 =聽1潞<sup></sup> was demonstrated for sample <strong>B</strong> with optimized parameters. The sensitivity of sample <strong>B</strong> was 1.56*10<sup>-7</sup>聽RIU when analyzing the direction of polarization plane. Note that the sensitivity of sample <strong>A</strong> was 2*10<sup>-6</sup>聽RIU when measuring the amplitude of transmitted wave.</p><br /><p></p><br /><p>Fig. 1.
