Background:

• Photonic crystal fibers (PCFs) offer unique light-confining properties for advanced sensor applications.
• Micro-porous core structures in PCFs enable enhanced interaction with analytes.
• Accurate characterization of PCF performance is crucial for developing effective chemical sensors.

Purpose of the Study:

• To investigate the performance of a novel micro-porous core photonic crystal fiber based chemical sensor.
• To analyze key optical parameters including relative sensitivity, confinement loss, numerical aperture, and effective area.
• To evaluate the sensor's potential for detecting various alcohol-based chemicals.

Main Methods:

• A folded cladding porous PCF structure with a circular air hole was designed and simulated.
• The finite element method (FEM) using COMSOL Multiphysics software was employed for numerical analysis.
• Anisotropic circular perfectly matched layer (A-CPML) boundary conditions were utilized for accurate simulations.

Main Results:

• The PCF demonstrated a high numerical aperture (NA) ranging from 0.35 to 0.36.
• Low confinement loss (CL) was observed, varying from approximately 10^-11 to 10^-7 dB/m.
• High effective area (A_eff) between 5.50 and 5.66 µm², along with specific V-parameter, Marcuse spot size (MSS), and beam divergence (BD) values, were obtained for alcohol series detection.

Conclusions:

• The proposed micro-porous core PCF exhibits excellent optical characteristics suitable for chemical sensing.
• The sensor shows promise for the selective detection of alcohol series within the E+S+C+L+U communication band.
• The simulation results highlight the potential of this PCF design for future high-performance chemical sensor development.
