Internet data traffic capacity is rapidly reaching limits imposed by optical fiber nonlinear effects. Having almost exhausted available degrees of freedom to orthogonally multiplex data, the possibility is now being explored of using spatial modes of fibers to enhance data capacity. We demonstrate the viability of using the orbital angular momentum (OAM) of light to create orthogonal, spatially distinct streams of data-transmitting channels that are multiplexed in a single fiber. Over 1.1 kilometers of a specially designed optical fiber that minimizes mode coupling, we achieved 400-gigabits-per-second data transmission using four angular momentum modes at a single wavelength, and 1.6 terabits per second using two OAM modes over 10 wavelengths. These demonstrations suggest that OAM could provide an additional degree of freedom for data multiplexing in future fiber networks.

互联网数据传输速率正在突破光纤非线性效应的极限.目前的技术几乎耗尽了所有正交多路数据传输的自由度,要提高光纤的数据传输率只能通过改变光纤的空间模式.我们证明了轨道角动量（orbital angular momentum,OAM）的创造出正交、不同空间分布的光束,可以结合多路复用光纤技术来传输数据.我们专门设计了超过1.1公里的耦合最小化光纤,在单波长4角动量模式下达到了每秒400G的速度,在超过十波长双轨道角动量模式下达到了每秒1.6T的速度.这些数据说明了轨道角动量可以为未来光纤网络中的多路数据传输提供更多的自由度.
