We analyze a theoretical and experimental reservoir computing architecture based on an add-drop silicon microring resonator. We test it with different datasets, including the recognition of flowers from the IRIS dataset.The information is transferred to the ring by means of a high power (>10mW) pump signal which generates non-linearities affecting a low-power continuous wave signal acting as a probe. The experimental setup was also simulated employing a time domain model [1] of the non-linear response of the ring to assess the physical limit of the pump power.
