Abstract
A photon communication system based on orbital angular momentum (OAM)-carrying beams is studied. We compartmentalize the atmospheric aberration into tilt,coma, astigmatism as well as defous. We numerically analyze the effects of tilt on the orbital angular momentum of communication beams and find that the tilt aberration can induce the noisy OAM. With the increasing of parameters P, L, the probability of initial OAM goes down while the effective number of noise OAM increases. At the same time, the peaks of the induced OAM probability (max-probability) are different as the P, L, changes. The increase of zenith angle damages the probability and leads to noisy OAM. This can also be applied to the impact of refractive index structure parameter. We also numerically analyze the effects which receiving-radius puts on the receiving probability of initial OAM through tilt aberration. Under the influence of tilt, the receiving probability of previous orbital angular momentum slashs with the receiving-radius becoming large.
