Description
This hands-on course dives into the experimental analysis of vortex beams, also known as optical beams carrying orbital angular momentum (OAM). These beams are used in high-capacity communication, optical trapping, microscopy, and quantum optics.
Topics covered
- Introduction to optical vortices and orbital angular momentum (OAM) fundamentals, physical interpretation of phase singularities and helical wavefronts
- Vortex beam generation techniques: spatial light modulators (SLMs), spiral phase plates, q-plates, diffractive optics, and digital holography
- Beam models and theory: Laguerre–Gaussian (LG), Bessel, and higher-order vortex beams, mode indices and topological charge concepts
- Experimental setup design: alignment procedures, beam shaping optics, calibration, and stability considerations in laboratory environments
- Measurement and characterization methods: interferometry, fork gratings, mode decomposition, intensity and phase profile analysis
- Propagation effects and distortions: turbulence influence, modal crosstalk, beam divergence, and compensation techniques
- Applications of vortex beams: high-capacity optical communication, optical trapping and tweezers, microscopy, imaging, and quantum optics demonstrations
- Practical lab exercises and data analysis workflows using simulation and experimental results
