Special Issue Information

Dear Colleagues,

We would like to invite you to submit your papers about optical sensors based on plasmonic gratings features to this Special Issue of the journal Sensors.

Plasmonic gratings play a crucial role for their application in optical sensors. Surface plasmon resonance (SPR) and localized SPR (LSPR) sensors have gained much popularity and are still flourishing due to advancements in nanofabrication technology. Optical regimes, such as diffraction in photonic crystals, absorption of plasmonic nanostructures, color switching systems, refraction of assembled birefringent nanostructures, and emission of nanomaterials, are of great interest, both for the pure scientific interest and for the many applications in which they are potentially involved. This Special Issue aims to be an opportunity to collect experimental and theoretical research works in these areas, giving space to the design, preparation, fabrication, characterization, simulations, and applications of these innovative and promising optical materials. This Special Issue addresses all the applications of optical sensors based on plasmonic gratins such as gas sensors (for the environment, for example), bio sensors for biological species (in liquid), or in situ monitoring of processes (temperatures measurement, thin films characterization….).

We invite you to submit a manuscript for this Special Issue; full papers, communications, and reviews are all welcome.

The focuses of this Special Issue include (but are not limited to) the following:

  • Photonic or plasmonic nanomaterials for sensing and biosensing;
  • Design of surface plasmon resonance (SPR) sensors;
  • Fabrication of SPR based diffraction grating (nanofabrication technology);
  • Preparation methods and applications for photonic or plasmonic-based sensors;
  • Theoretical simulations of photonic and plasmonic nanostructures for sensing;
  • Other hybrid materials in plasmonic sensors, for example, transition metal nitrides (TiN…).

Surface plasmon resonance is an effect widely used for biosensing. Biosensors based on this effect operate in different configurations, including the use of diffraction gratings as couplers. Gratings are highly tunable and are easy to integrate into a fluidic system due to their planar configuration. We discuss the optimization of plasmonic grating couplers for use in a specific sensor configuration based on the optical switch. These gratings present a sinusoidal profile with a high depth/period ratio. Their interaction with a p-polarized light beam results in two significant diffracted orders (the 0th and the −1st), which enable differential measurements cancelling noise due to common fluctuations. The gratings are fabricated by combining laser interference lithography with nanoimprinting in a process that is aligned with the challenges of low-cost mass production. The effects of different grating parameters such as the period, depth and profile are theoretically and experimentally investigated. Full article
