Light-scattering Mueller matrix from a fiber as a function of MgO contamination

Area of Science:

• * Optical physics and light scattering phenomena.
• * Materials science, focusing on crystalline contaminants and their effects on optical properties.

Background:

• * The light-scattering Mueller matrix of a quartz fiber is sensitive to its physical properties.
• * Understanding how contaminants affect optical measurements is crucial for accurate material characterization.

Purpose of the Study:

• * To investigate the impact of magnesium oxide (MgO) crystal contamination on the light-scattering Mueller matrix of a quartz fiber.
• * To quantify how contamination alters the optical signature of the quartz fiber.

Main Methods:

• * Measurement of the light-scattering Mueller matrix for a quartz fiber (radius = 0.345 microm) at a wavelength of lambda = 0.4416 microm.
• * Systematic introduction of MgO crystal contamination to observe changes in the Mueller matrix elements.

Main Results:

• * Low MgO contamination mimicked a larger quartz fiber radius in the Mueller matrix.
• * Contamination introduced high-frequency, low-amplitude oscillations, obscuring the low-frequency oscillations of an uncontaminated fiber.
• * Observed scattering of light outside the plane of incidence due to MgO contamination.

Conclusions:

• * MgO contamination significantly alters the light-scattering Mueller matrix of quartz fibers.
• * Contaminants can mask intrinsic fiber properties and introduce artifacts in optical measurements.
• * The study highlights the importance of sample purity in Mueller matrix scattering analysis.
