Paper Abstract

In this paper, we introduce a novel method for free-space optic communication. Normally, the free-space optic communication is sensitive to atmospheric turbulence. In order to overcome the weakness, we utilize two differential modulation optical beams, which improve markedly the quality of free-space optic communication. The experiments, based on two wave mixing scheme were1 done using photorefractive crystal LiNbO3. Photorefractive grating will be changed with the electrical signals, which will results in the energy transfer process between two beams, and then form two differential modulation optical beams. Firstly, we will present a brief introduction to the theoretical arguments for energy transfer process in two wave mixing experiments. After briefly explaining the method to achieve two differential modulation optical beams we discuss the experiments for free-space optic communication. Finally, we conclude that the novel method improve markedly the quality of free-space optic communication.
