Summary:
In this contribution, we investigate the computational abilities of semiconductor ring lasers with optical delayed feedback for machine learning tasks. We benchmark our system on a chaotic time series prediction task. The results show that, as other types of lasers, good performance can be obtained in a broad range of the key parameters. In particular, we find that fast processing speed of 0:5 GSample/s can be achieved. This is obtained even for an overall delay loop of 2 ns. With this short delay, it is possible to implement this reservoir computing schemes on chip as both the semiconductor ring lasers and such a short delay can be easily implemented on the same chip.
