Abstract The twist phase has recently exhibited better resistance to turbulence-induced degeneration of the signal mode in orbital angular momentum (OAM) spectra. However, our attention is paid to exploring the combined influence of the twist factor and noncanonical strength on “distorted dislocation” and OAM spectra in non-Kolmogorov atmospheric turbulence by introducing a noncanonical vortex-pair to twisted partially coherent beams. It is found that the twist factor or noncanonical strength can distort concentric ring dislocations in spatial correlation singularities into the so-called “distorted dislocations”. In turbulence propagation, noncanonical strengths can lead to annihilation and creation of distorted dislocations and change the number of dislocations, but twist factors cannot affect their number except for deepening the distortion in the structures. The explicit expression of the OAM flux density per photon, which was also derived, indicates that noncanonical strength can further improve the OAM capacity even if the twist factor reaches its extreme value. Compared to the twist factor, the noncanonical strength plays a more significant role in the signal modulation and detectivity of OAM spectra. If the combined effect of the twist factor and noncanonical strength is considered, the detection performance of the signal mode during long-distance turbulence propagation is distinctly better than that of only the twist factor or the noncanonical strength. The noncanonical strength should not be ignored due to its better performance in the OAM capacity and detection probability of the signal mode. This work may provide inspiration for OAM-based optical communication by the modulation of multi-degrees of freedom associated with noncanonical strengths and twist factors.

Online attention
Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
