We predict that semiconductor Fano lasers can be used to realize an all-optical non-linear activation function for neuromorphic photonic computing. By exploiting optical control of a Fano mirror, the laser can generate optical pulses with low threshold energy, gigahertz repetition rates, and orders of magnitude suppression between the on- and off-states. Analytical estimates of the switching threshold energy, extinction ratio, and refractory period agree well with numerical results.
我们预测，半导体法诺激光器可用于实现用于神经形态光子计算的全光非线性激活函数。通过利用法诺镜的光学控制，该激光器可产生具有低阈值能量、千兆赫兹重复率以及开态和关态之间数量级抑制的光脉冲。开关阈值能量、消光比和不应期的分析估计与数值结果吻合良好。
