High-Q-factor Silicon-On-Insulator microrings both self-pulsate and are excitable. In this paper, we experimentally demonstrate that this excitability is cascadable. Moreover;we show how, using a Coupled Mode Theory description of the ring, an adiabatic elimination of the fast field variable allows to calculate both the self-pulsation and the excitability
onsets. The excitability region of a micro ring is merely centered at the blue-side of the
ring's resonance, as the self-pulsation onset there is a subcritical Andronov-Hopfbifurcation.
A proper characterization of this excitability will help to understand how microrings could be used as a basic component in photonic spiking neural networks.
