Abstract:
|
We study experimentally a semiconductor laser operating in a feedback-induced regime known as low frequency fluctuations (LFFs), in which the laser emits a spiking output that resembles the spikes of biological neurons. We analyze the response to a weak periodic signal that is directly applied to the laser pump current, as a function of the frequency of the signal, and discuss the observations in relation to the response of sensory neurons. |
