Abstract

Modulating retroreflector (MRR) free-space optical (FSO) communication systems have attracted attentions in asymmetric optical wireless communication applications. However, the double-pass atmospheric propagation and the planar modulator in the MRR FSO communication system led to relatively large turbulence-induced fading and relatively low modulation efficiency. This work combines an adaptive optics phase compensation method with an orbital angular momentum (OAM) generation method at the MRR terminal by using a spatial light modulator with optical retroreflectors to achieve the fading mitigation and the OAM transmission. The adaptive optics aided OAM generation approach is carried out in wave-optics simulation and the simulation results show that the approach provides a significant phase compensation effect and an improved OAM mode purity at the transceiver. It is evident that the proposed approach could considerably reduce the impact of atmospheric turbulence on OAM wavefront and promote the application of OAM modes in MRR FSO communication systems.
