“…Magneto-optical interactions with propagative plasmons have been also studied in grating structuration [128,129]. Nevertheless, only a few (theoretical) magneto-plasmonic structures were proposed in waveguiding configurations [130,131]. The main interest in these MO or magnetoplasmonic structures is to realize integrated non-reciprocal transmission of light, like optical isolation or circulation.…”

The development of integrated, compact, and multifunctional photonic circuits is crucial in increasing the capacity of all-optical signal processing for communications, data management, and microsystems. Plasmonics brings compactness to numerous photonic functions, but its integration into circuits is not straightforward due to insertion losses and poor mode matching. The purpose of this article is to detail the integration strategies of plasmonic structures on dielectric waveguides, and to show through some examples the variety and the application prospect of integrated plasmonic functions.

“…They represent collective oscillations of electromagnetic fields and conduction electrons propagating at the interface between a metal and a dielectric. The strong sensitivity of the SP to the dielectric permittivity at the metal/dielectric interface enables SP wavevector modulation in the presence of the magnetic field. − The magnetic field control of SP propagation becomes feasible by implementing magnetic materials in plasmonic crystals or thin metal films. Such magnetoplasmonic systems open up a range of approaches for controlling magneto-optical effects.…”

We report on how observation of the Goos−Hanchen (GH) shift can be used to spatially resolve the transverse magneto-optical Kerr effect (TMOKE) enhancement in all-nickel magnetoplasmonic crystals (MPCs). First, the excitation of surface plasmons in the MPCs leads to a 15.3 μm (18λ) GH shift. Then, in the presence of a transverse magnetic field, the modulation of the lateral spatial intensity distribution of the reflected light [TMOKE(x)], caused by the GH shift, reaches 4.7% in the experiment. The spatially resolved TMOKE(x) values are several times higher compared to those from conventional TMOKE measurements in the MPCs. The concept of the spatially resolved magneto-optical effects under GH shift can be further extended to other magnetophotonic nanodevices for additional enhancing magneto-optical effects, sensing, and light modulation applications.

“…In recent years, magneto-plasmonic nanoparticles have gained significant attention in biosensing, emerging as versatile tools for detecting and analyzing biological molecules. [1][2][3][4][5] These nanoparticles combine the key characteristics of two crucial phenomena: plasmonics exhibited by metal nanoparticles (NPs) and magnetic properties of nanocrystals of 3d metals and their oxides. [6,7] The outstanding optical properties of metal NPs primarily arise from the localized surface plasmon resonance (LSPR) effect.…”

Magneto‐plasmonic particles, comprising gold and iron oxide, exhibit substantial potential for biosensing applications due to their distinct properties. Gold nanoparticles (AuNPs) provide plasmonic features, while iron oxide composites, responsive to an external magnetic field, significantly reduce detection time compared to passive diffusion. This study explores core@satellite magneto‐plasmonic particles (CSMPs), featuring magnetic nanoparticle clusters and numerous satellite‐like AuNPs, to amplify the optical response on a nanostructured gold surface. Using a sandwich scheme, target analytes are detected as hybrid nanoparticles bind to the pre‐immobilized target on the AuNPs surface, inducing changes in the immunosensor's extinction spectrum. Application of an external magnetic field notably enhances biosensor response and sensitivity, reducing assay time from hours to minutes. Leveraging the properties of CSMPs, the immunosensor detects specific immune protein at low concentrations within minutes. CSMPs hold considerable promise for precise and sensitive analyte detection, offering potential applications in rapid testing and mass screening.
