偏振是光的一种基本性质。与众所周知的空间均匀的线偏振、圆偏振和椭圆偏振不同，具有空间可变偏振态的矢量光束因其扩展的功能而受到越来越多的关注。在这封信中，我们提出了一种利用高基矢量波束编码/译码的可见光通信链路。利用单一的纯位相空间光调制器，我们产生了16个状态的矢量光束，代表十六进制数。在可见光通信链路实验中，我们传输了一个具有10,000个十六进制数的随机高基数序列和一个具有8,192个十六进制数的x像素Lena灰度图像。对误码率进行了评估，并在所有接收的十六进制数中实现了零误码，显示了使用高基数矢量波束编解码的良好链路通信性能。(C)2015年美国光学学会
Polarization is a basic property of light. Different from well-known linear, circular, and elliptical polarizations, which are spatially homogeneous, a vector light beam with spatially variant polarization states has received increasing interest for its expanded functionalities. In this Letter, we present a visible-light communication link exploiting high-base vector beam encoding/decoding. Using a single phase-only spatial light modulator, we generate 16 states of vector beams representing hexadecimal numbers. In the visiblelight communication link experiment, we transmit a random high-base number sequence with 10,000 hexadecimal numbers and a 64 x 64 pixel Lena gray image with 8192 hexadecimal numbers. The bit error rate is evaluated, and zero error among all received hexadecimal numbers is achieved, showing favorable link communication performance using the high-base vector beam encoding/decoding.
