We present experiments on reservoir computing (RC) using a network of vertical-cavity surface-emitting lasers (VCSELs) that we diffractively couple via an external cavity. Our optical reservoir computer consists of 24 physical VCSEL nodes. We evaluate the system’s memory and solve the 2-bit XOR task and the 3-bit header recognition (HR) task with bit error ratios (BERs) below 1% and the 2-bit digital-to-analog conversion (DAC) task with a root mean square error (RMSE) of 0.067.

使用衍射耦合 VCSEL 进行实验油藏计算

我们使用垂直腔表面发射激光器(VCSEL)网络进行储层计算(RC)实验,我们通过外腔进行衍射耦合。我们的光储层计算机由 24 个物理 VCSEL 节点组成。我们评估系统的内存并解决误码率 (BER) 低于 1% 的 2 位 XOR 任务和 3 位标头识别 (HR) 任务,以及 2 位数模转换 (DAC) 任务均方根误差 (RMSE) 为 0.067。
