Area of Science:

  • Optics and Photonics
  • Fiber Optic Sensing
  • Plasmonics

Background:

  • Conventional single-mode fibers support high-order cladding modes in semi-degenerate pairs, typically radially or azimuthally polarized.
  • Exciting these distinct polarization modes separately is crucial for advanced sensing applications.

Purpose of the Study:

  • To investigate the effect of plasmonic coupling on fiber cladding modes.
  • To develop a precise wavelength reference for enhanced refractometric and biochemical sensing.
  • To demonstrate a highly sensitive biomolecular detection method using plasmon-assisted fiber Bragg gratings.

Main Methods:

  • Utilizing tilted fiber Bragg gratings to selectively excite radial and azimuthal polarization modes.
  • Applying a thin gold coating to induce plasmonic coupling and modify mode effective indices.
  • Identifying a unique
  • apolarized
  • grating resonance with polarization-independent effective index.
  • Proposing two plasmon interrogation methods based on wavelength and amplitude measurements.
  • Conducting a biotin-streptavidin experiment for biomolecular recognition analysis.

Main Results:

  • Plasmonic coupling differentially modifies effective indices based on polarization and mode order.
  • The
  • apolarized
  • resonance serves as a direct indicator of surface plasmon excitation and an absolute wavelength reference.
  • Differential spectral transmission measurements near the apolarized resonance enable highly accurate sensing.
  • Achieved picomolar (pM) concentration detection and sensitivity to refractive index changes as low as 10(-5).

Conclusions:

  • Plasmon-assisted tilted fiber Bragg gratings offer a robust platform for high-sensitivity biosensing.
  • The
  • apolarized
  • resonance is key for precise localization of sensing resonances.
  • The proposed differential spectral transmission method significantly enhances sensing accuracy and sensitivity.
