All-optical non-linear activation function for neuromorphic photonic computing using semiconductor Fano lasers
T. Rasmussen, Yi Yu, Jesper Mørk
Abstract
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.
