High-Speed Reservoir Computing with Spin-VCSELs
Krishan Harkhoe, Guy Verschaffelt, Guy Van der Sande · 2021
We introduce a reservoir computing scheme where a VCSEL with optical spin injection and delayed optical feedback serves as a reservoir. Polarization modulation is considerably faster than intensity modulation, allowing a tenfold increase of processing speed. The performance is benchmarked using timeseries prediction tasks.
