General Astigmatic Fields and Twist

Call for Papers

General astigmatic fields are electromagnetic waves with an elliptically shaped amplitude and phase fronts. These two ellipses are different and propagate differently. This field transports orbital angular momentum (twist), depending on the degree of astigmatism and intrinsic angular momentum, related to the polarization. These properties hold also for the single photon of the beam. In the recent years, powerful laser systems in the fundamental mode were realized. They can be transformed into beams with large orbital angular momentum of interest for many applications in science and technology, such as particle manipulation, quantum information, and optical communication. Potential topics include, but are not limited to:

  • Theoretical papers on twist, including quantization, twist of coherent, incoherent, and multi-mode fields
  • Generation of beams with orbital angular momentum
    • Astigmatic laser systems with twist
    • Transformation by optical systems
    • Holographic generation
    • Characterization of twisted beams
  • Applications
    • Particle manipulation
    • Optical communication
    • Quantum information
    • Optical storage
