We experimentally demonstrate the possibility to process two tasks in parallel with a photonic reservoir computer based on a vertical-cavity surface-emitting laser (VCSEL) as a physical node with time-delay optical feedback. The two tasks are injected optically by exploiting the polarization dynamics of the VCSEL. We test our reservoir with the very demanding task of nonlinear optical channel equalization as an illustration of the performance of the system and show the recover of two signals simultaneously with an error rate of 0.3% (3%) for a 25 km-fiber distortion (50 km-fiber distortion) at a processing speed of 51.3 Mb/s.

光子存储计算机实现双任务处理的实验实现

我们实验证明了与基于垂直腔面发射激光器（VCSEL）的光子储能计算机并行处理两个任务的可能性，该激光器作为具有延迟光反馈的物理节点。通过利用VCSEL的偏振动力学，光学地注入了两个任务。我们以非常苛刻的非线性光信道均衡任务来测试我们的储层，以说明系统的性能，并显示了25 km光纤畸变时两个信号的同时恢复率以及0.3％（3％）的误码率（ 50 km-光纤失真），处理速度为51.3 Mb / s。
