Abstract

We establish a general framework for introducing novel, to the best of our knowledge, classes of beams possessing precisely tailored coherence–orbital angular momentum (COAM) matrices, with the help of Bochner’s theorem. The theory is illustrated by several examples relating to COAM matrices having a finite and infinite number of elements.
