Timing jitter and pump–cavity desynchronization in pulse-driven reservoir computing

Investigate systematically how timing jitter and pump–cavity desynchronization affect the information-processing performance, stationary states, spectral characteristics, and temporal drift of the frequency-multiplexed reservoir computer based on a synchronously pulse-driven Kerr optical cavity.

Background

The study evaluates intracavity amplified-spontaneous-emission noise and detection-stage noise but does not model timing imperfections. In a synchronously pulse-driven cavity, timing jitter can disrupt the coherent accumulation of resonantly enhanced linear cavity modes, while pump–cavity desynchronization can alter the dynamical operating conditions.

The authors identify pump–cavity desynchronization as an important control parameter in pulse-driven Kerr resonators and leave a systematic investigation of timing jitter and desynchronization in the proposed reservoir-computing configuration for future work. Such an investigation would characterize how these effects modify the cavity state and the resulting information-processing capacity.
