摘要：
As an alternative to classical LP-modes used as a signal carrier in the optical fiber, we propose a superposition of angular harmonics that can be obtained as a special combination of LP-modes, which also shows modal properties in an optical fiber. Results of a number of natural experiments on selective excitation of both individual angular harmonics and their superposition are discussed.
