RT Journal Article T1 Rotating beams in isotropic optical system A1 Alieva Krasheninnikova, Tatiana A1 Abramochkin, Eugeny A1 Asenjo García, Ana A1 Razueva, Evgeniya AB Based on the ray transformation matrix formalism, we propose a simple method for generation of paraxial beams performing anisotropic rotation in the phase space during their propagation through isotropic optical systems. The widely discussed spiral beams are the particular case of these beams. The propagation of these beams through the symmetric fractional Fourier transformer is demonstrated by numerical simulations.
