Synthesis and characterization of non-uniformly totally polarized light beams: tutorial

Area of Science:

• Optics and Photonics
• Quantum Optics

Background:

• Traditional light polarization assumes uniform states across the beam's transverse section, simplifying propagation to a scalar problem under paraxial approximation.
• Recent decades have seen significant interest in light beams with spatially variant polarization states due to their utility in optical trapping, laser machining, nanoscale imaging, and polarimetry.

Purpose of the Study:

• To provide an introductory treatment of non-uniformly totally polarized beams.
• To review parameters for characterizing polarization distribution (local and global).
• To describe methods for generating these beams.

Main Methods:

• Review of existing literature and theoretical frameworks for polarized light.
• Description of characterization parameters for polarization distribution.
• Overview of generation techniques for non-uniformly polarized beams.

Main Results:

• Introduction to the concept and importance of non-uniformly totally polarized beams.
• Discussion of methods to quantify and analyze their polarization characteristics.
• Presentation of various techniques for their experimental generation.

Conclusions:

• Non-uniformly totally polarized beams represent a significant area of study beyond traditional uniform polarization.
• Characterization and generation methods are essential for harnessing their potential in diverse optical applications.
• This tutorial serves as a foundational resource for researchers entering this field.
