Enhanced performance of a reservoir computer using polarization dynamics in VCSELs
Jeremy Vatin, Damien Rontani, Marc Sciamanna · Optics Letters · 2018
We analyze the performance of a reservoir computer based on time-delay feedback and optical injection, which is drawing benefits from the high-speed polarization dynamics of a vertical cavity surface emitting laser. We show that such a system has high computation performance and yields deeper memory than an existing single-mode laser-based reservoir computer. Performance is demonstrated on several benchmarking tasks. In particular, the error rate is an order of magnitude smaller when performing channel equalization.
