Long Zhu, Andong Wang, Jian Wang

摘要:

近几年来,近红外光束在光学操纵、光学成像、光学布线、微机械加工、等离子体产生和非线性光学等领域有着广泛的应用。通过利用弯曲光束而不是传统的高斯光束进行视线光通信,在这里,我们提出并证明了自由空间数据承载可弯曲光通信的可行性,沿着任意轨迹具有多种功能。采用39.06Gbit/s的32进制正交幅度调制(32-QAM)离散多音(DMT)信号,在3种不同弯曲光路下,实现了自由空间可弯曲光强度调制直接检测(IM-DD)通信系统。此外,我们还描述了自由空间可弯曲光通信的多种功能,包括旁路障碍传输、自愈传输、自断轨迹传输和可移动多接收器传输。观察结果表明,可弯曲光束可以使自由空间光通信更灵活,更鲁棒和更多功能。这些演示可能会打开一扇大门,探索更多特殊的光束,使先进的自由空间光通信具有更强的灵活性,鲁棒性和功能性。

英文摘要:

Bendable light beams have recently seen tremendous applications in optical manipulation, optical imaging, optical routing, micromachining, plasma generation and nonlinear optics. By exploiting curved light beams instead of traditional Gaussian beam for line-of-sight light communications, here we propose and demonstrate the viability of free-space data-carrying bendable light communications along arbitrary trajectories with multiple functionalities. By employing 39.06-Gbit/s 32-ary quadrature amplitude modulation (32-QAM) discrete multi-tone (DMT) signal, we demonstrate free-space bendable light intensity modulated direct detection (IM-DD) communication system under 3 different curved light paths. Moreover, we characterize multiple functionalities of free-space bendable light communications, including bypass obstructions transmission, self-healing transmission, self-broken trajectory transmission, and movable multi-receiver transmission. The observed results indicate that bendable light beams can make free-space optical communications more flexible, more robust and more multifunctional. The demonstrations may open a door to explore more special light beams enabling advanced free-space light communications with enhanced flexibility, robustness and functionality.
