The stability of the ultrafast spiking effect in membrane III- V lasers on Si with optical feedback is experimentally evaluated for neuromorphic spiking neural network PICs. Stable operation, spiking thresholds, and refractory periods are obtained in two different lasers and at two different bias current regions.
