“…[131][132][133][134][135] Since noble metals exhibit smaller losses than FM metals, hybrid noble-FM metallic nanostructures have also been exploited for magnetoplasmonic approaches. 46,53,77,136,137 These works have motivated various applications, including sensing, 51,61,78,115,138,139 telecommunications, [140][141][142][143][144] and magnetometry. 145,146 It is significant that the large losses from hybrid magnetoplasmonic nanostructures, considered a major drawback for biosensing, are suitable for nanoparticle-based hyperthermia and drug delivery.…”

Magnetic nanostructures sustaining different types of optical modes have been used for magnetometry and label-free ultrasensitive refractive index probing, where the main challenge is the realization of compact devices that are able to transfer this technology from research laboratories to smart industry. This Perspective discusses the state-of-the-art and emerging trends in realizing innovative sensors containing new architectures and materials exploiting the unique ability to actively manipulate their optical properties using an externally applied magnetic field. In addition to the well-established use of propagating and localized plasmonic fields, in the so-called magnetoplasmonics, we identified a new potential of the all-dielectric platforms for sensing to overcome losses inherent to metallic components. In describing recent advances, emphasis is placed on several feasible industrial applications, trying to give our vision on the future of this promising field of research merging optics, magnetism, and nanotechnology.

“…Micro-ring resonators (MRR), serving as essential photonic building blocks, are extensively employed in a wide array of optical devices, encompassing filters, m odulators, s witches, a nd sensors. 1,2 T hese v ersatile structures boast a plethora of advantages, including their compact form factor, exceptional Q factor, minimal power consumption, and seamless integration with conventional silicon microfabrication techniques. In this context, silicon nitride (Si 3 N 4 ) photonic platforms have emerged as a particularly attractive option, owing to the waveguide material's ability to facilitate on-chip photonic circuitry while exhibiting remarkably low losses within the nearinfrared (NIR) region and across the entire visible spectral range.…”

Micro-ring resonators (MRR) are basic photonic components, which serve as crucial building blocks for a variety of devices, e.g. integrated sensors, external cavity lasers, and high speed photonic data transmitters. Silicon nitride photonic platforms are particularly appealing in this field o f a pplication, s ince t his w aveguide material enables on-chip photonic circuitry with (ultra-) low losses in the NIR as well as across the whole visible spectral range. In this contribution we investigate key performance properties of MRRs in the wavelength range around 850 nm, such as free spectral range (FSR), quality factor (Q factor) and extinction ratio. We systematically investigate a large parameter space given by the MRR radii, coupling gaps between ring and bus waveguide, as well as waveguide width. Furthermore, we compare key properties such as the Q factor between low pressure chemical vapor deposition (LPCVD) and plasma enhanced chemical vapor deposition (PECVD) Si 3 N 4 platforms and find enhanced values for LPCVD ring resonators reaching nearly a Q factor of 10 6 .The fabrication is carried out with standard CMOS foundry equipment, utilizing photolithography and reactive ion etching on 250 nm thick silicon nitride films. A s c ladding m aterial, h igh d ensity P ECVD s ilicon o xide i s d eposited p rior t o the waveguide onto bare silicon and a sputtered oxide serves as upper cladding. With this process toolbox full CMOS backend compatibility is achieved when considering only PECVD Si 3 N 4 waveguide material. In terms of manufacturability, special focus is put on the die-to-die as well as on wafer-to-wafer variability of the performance parameters, which is crucial when considering mass production of MRR devices. Finally, the experimental findings are compared to finite difference time domain (FDTD) simulations of the MRR circuits revealing excellent agreement when considering the manufacturing variability.

“…Despite these advances, magnetoplasmonic applications are still hampered by the intrinsic losses of metallic inclusions, which has motivated the search for new materials and structures to overcome these challenges. In particular, the reduced level of losses from dielectric ferromagnetic materials [32][33][34][35], combined with their integrability with silicon photonics [36,37], has motivated a lot of recent research [38][39][40][41][42][43]. Moreover, the design and development of hyperbolic MO metamaterials has also gained interest during the last few years [44][45][46][47][48].…”

Magneto-optics (MO) is an effervescent research field, with a wide range of potential industrial applications including sensing, theranostics, pharmaceutics, magnetometry, and spectroscopy, among others. This review discusses the historical development, from the discovery of MO effects up to the most recent application trends. In addition to the consolidated fields of magnetoplasmonic sensing and modulation of optical signals, we describe novel MO materials, phenomena, and applications. We also identified the emerging field of all-dielectric magnetophotonics, which hold promise to overcome dissipation from metallic inclusions in plasmonic nanostructures. Moreover, we identified some challenges, such as the need to merge magneto-chiroptical effects with microfluidics technology, for chiral sensing and enantioseparation of drugs in the pharmaceutical industry. Other potential industrial applications are discussed in light of recent research achievements in the available literature.
