Generation of vector beams using synthetic phase holograms

Area of Science:

• Optics and Photonics
• Holography
• Vector Field Generation

Background:

• Synthetic phase holograms (SPHs) offer a versatile platform for optical field manipulation.
• Generating complex vector fields with precise control remains a challenge in optics.

Purpose of the Study:

• To introduce and evaluate a class of SPHs for generating vector fields.
• To demonstrate the application of SPHs in creating vector Bessel beams.

Main Methods:

• Encoding transverse vector field components onto SPHs using linear phase carriers.
• Modulating spatially separated components with orthogonal polarizations.
• Collinearly combining components to form the final vector field.

Main Results:

• SPHs effectively encode and generate vector fields with high efficiency and accuracy.
• Experimental generation of vector Bessel beams using a phase spatial light modulator setup.
• Demonstrated control over polarization and spatial properties of generated vector fields.

Conclusions:

• The proposed SPH approach provides a robust method for vector field generation.
• This technique is well-suited for applications requiring tailored optical beams, such as vector Bessel beams.
