Area of Science:

  • Plasmonics
  • Nanophotonics
  • Optical Sensing

Background:

  • Surface plasmon polaritons (SPPs) are crucial for plasmonic devices.
  • One-dimensional plasmonic gratings offer tunable optical properties.
  • Refractive index sensing requires sensitive and selective detection methods.

Purpose of the Study:

  • To investigate 1D plasmonic gratings for refractive index sensing.
  • To correlate numerical simulations with experimental SPP excitation.
  • To explore the effect of grating depth on SPP resonance characteristics.

Main Methods:

  • Fabrication of silver-coated polysilicon gratings with varying depths (50-375 nm).
  • Excitation of SPPs using a tunable quantum cascade laser (QCL) in the mid-infrared.
  • Measurement of angle-resolved specular reflectance spectra.

Main Results:

  • Experimental SPP resonance spectra agree well with numerical simulations.
  • Shallower gratings exhibit narrower SPP resonances (e.g., 2.9 nm FWHM).
  • Predicted spectral shift of 4122 nm/RIU, yielding a figure of merit (FOM) of ~1421 RIU⁻¹.

Conclusions:

  • 1D plasmonic gratings are viable for sensitive refractive index sensing.
  • Grating depth is a key parameter for tuning SPP resonance bandwidth.
  • Industrial-scale microfabrication processes enable mass production of plasmonic sensors.
