As a means of increasing the channel capacity in free-space optical communication systems, two types of orbital angular momentum carrying beams, Bessel-Gauss and Laguerre-Gauss, are studied. In a series of numerical simulations, we show that Bessel-Gauss beams, pseudo-nondiffracting beams, outperform Laguerre-Gauss beams of various orders in channel efficiency and bit error rates.
作为一种增加自由空间光通信系统信道容量的方法，研究了两种携带轨道角动量的光束，即贝塞尔 - 高斯光束和拉盖尔 - 高斯光束。在一系列数值模拟中，我们表明，贝塞尔 - 高斯光束，即伪无衍射光束，在信道效率和误码率方面优于各种阶数的拉盖尔 - 高斯光束。
