Impact of Free-carrier Nonlinearities on Silicon Microring-based Reservoir Computing

2023-07-13 · Bernard J. Giron Castro, Christophe Peucheret, Darko Zibar, Francesco Da Ros

We quantify the impact of thermo-optic and free-carrier effects on time-delay reservoir computing using a silicon microring resonator. We identify pump power and frequency detuning ranges with NMSE less than 0.05 for the NARMA-10 task depending on the time constants of the two considered effects.
