Special Issue Information

Dear Colleagues,

Nanostructured materials for plasmonic/photonic applications have become a new research paradigm poised to transform current technologies. Nanofabrication and characterization of such structures are crucial to boost the performances of optical nanosystems.

There is a strong interest in the unconventional optical properties of chiral metamaterials, alternative plasmonic nanostructures (beyond noble metals), hybrid nanostructures and novel 2D or 3D nanostructure arrangements.

This Special Issue provides the possibility to highlight the most recent theoretical and experimental developments in the optical properties of plasmonic/photonic nanosystems and nanomaterials and to discuss their potential applications.

In this Special Issue, we expect to cover a variety of topics:

  • Chiral metamaterials;
  • Plasmonic and photonic nanostructures;
  • Nanostructures for strong light–matter coupling;
  • Hybrid nanophotonics;
  • Plasmonic/photonic nanostructures for sensing, energy and hydrogen production.

We look forward to receiving your contributions.

Over the past few decades, advances in various nanophotonic structures to enhance light–matter interactions have opened numerous opportunities for biosensing applications. Beyond the successful development of label-free nanophotonic biosensors that utilize plasmon resonances in metals and Mie resonances in dielectrics, simpler structures are required to achieve improved sensor performance and multifunctionality, while enabling cost-effective fabrication. Here, we present a simple and effectual approach to colorimetric biosensing utilizing a trilayered Gires–Tournois (GT) resonator, which provides a sensitive slow-light effect in response to low refractive index (RI) substances and thus enables to distinguish low RI bioparticles from the background with spatially distinct color differences. For low RI sensitivity, by impedance matching based on the transmission line model, trilayer configuration enables the derivation of optimal designs to achieve the unity absorption condition in a low RI medium, which is difficult to obtain with the conventional GT configuration. Compared to conventional bilayered GT resonators, the trilayered GT resonator shows significant sensing performance with linear sensitivity in various situations with low RI substances. For extended applications, several proposed designs of trilayered GT resonators are presented in various material combinations by impedance matching using equivalent transmission line models. Further, comparing the color change of different substrates with low RI NPs using finite-difference time-domain (FDTD) simulations, the proposed GT structure shows surpassing colorimetric detection.
