Polarimetric parameters associated to special microstructured fibers.

Area of Science:

• Optics and Photonics
• Materials Science

Background:

• Microstructured fibers offer unique light guiding properties.
• Polarimetric characterization is crucial for understanding fiber behavior.

Purpose of the Study:

• To determine Mueller matrices for homemade index-guiding microstructured fibers.
• To analyze polarimetric parameters and their relationship with fiber properties.

Main Methods:

• Measurement of Mueller matrices at 1550 nm transmission wavelength.
• Calculation of diattenuation, polarizance, and polarization-dependent loss.
• Correlation analysis between fabrication parameters and polarimetric output.

Main Results:

• Mueller matrices were successfully determined for six different fibers.
• Key polarimetric parameters were quantified for a 2m fiber length.
• A significant inverse relationship was found between output degree of polarization (DoP) and the d/Λ value.

Conclusions:

• Fiber fabrication parameters directly influence the output DoP.
• The d/Λ ratio is a critical factor affecting polarization characteristics in these fibers.
• Results provide insights for designing microstructured fibers with controlled polarization behavior.
