研究目的
Investigating the performance of a high order Bessel Gaussian beam used in underwater optical communication, focusing on the effects of oceanic turbulence on the probabilities of the signal and crosstalk orbital angular momentum (OAM) states.
研究成果
The study concludes that the probabilities of the signal and crosstalk OAM states of a Bessel Gaussian beam are affected by propagation distance and oceanic turbulence parameters. The use of a receiver aperture can reduce crosstalk OAM states while maintaining the signal OAM states' probability, potentially improving underwater optical communication systems.
