We have analyzed the performance of a reservoir computing system based on a semiconductor laser with
delayed optical output feedback on timeseries prediction and bit parity tests. Both laser and feedback
section are fully integrated on an InP based photonic chip fabricated on the Jeppix platform. We have
studied how the system parameters affect the performance and found that this reservoir computing chip
reaches processing speeds of 0.9GSa/s with comparable performances as obtained by other non-integrated
RC setups based on delayed feedback as well as RC setup on passive silicon photonic chips.
