This study presents a new method for building photonic crystal fiber (PCF) sensor arrays. These fiber optic sensors enable the creation of robust sensor networks for detecting various environmental changes.

Area of Science:

  • Photonics
  • Fiber Optics
  • Sensor Technology

Background:

  • Photonic crystal fibers (PCFs) offer unique light manipulation properties.
  • Developing robust and scalable fiber optic sensor networks remains a challenge.

Purpose of the Study:

  • To present an alternative method for constructing point and sensor array devices using PCFs.
  • To demonstrate the feasibility of creating multiplexed fiber optic sensor networks.

Main Methods:

  • A short segment of index-guiding PCF (9-12 mm) was fusion spliced between standard single-mode fibers.
  • Selective excitation and overlapping of specific modes within the PCF were employed.
  • The transmission spectra were analyzed to identify a single, narrow notch characteristic.

Main Results:

  • The developed sensors exhibited a single, narrow notch in their transmission spectra.
  • The notch position was sensitive to external perturbations, enabling parameter sensing.
  • High extinction ratio (>30 dB) and low insertion loss facilitated series sensor placement.

Conclusions:

  • This PCF-based method allows for the creation of highly sensitive and multiplexed fiber optic sensors.
  • The technique enables the practical implementation of distributed sensor networks for diverse applications.
  • The sensors offer a promising alternative for advanced optical sensing systems.
