为了提高自由空间光通信的信道容量，提出了利用锥形折射实现偏振解复用和偏振复用。该技术是基于前向-后向光学变换发生时，光束连续沿着光轴传播的两个相同的双轴晶体的锥形折射特征向量的方向相反。我们提出了一个实验证明的有用性的锥形折射解复用和复用技术，通过增加一个数量级的信道容量在光频率在4米的传播距离。(C)2012美国光学学会
Polarization demultiplexing and multiplexing by means of conical refraction is proposed to increase the channel capacity for free-space optical communication applications. The proposed technique is based on the forward-backward optical transform occurring when a light beam propagates consecutively along the optic axes of two identical biaxial crystals with opposite orientations of their conical refraction characteristic vectors. We present an experimental proof of usefulness of the conical refraction demultiplexing and multiplexing technique by increasing in one order of magnitude the channel capacity at optical frequencies in a propagation distance of 4 m.
