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 using standard building blocks. 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.
