Abstract
To realize a reservoir computing system with a small size and reduced learning cost, provided is a laser apparatus including a laser; a feedback waveguide that is operable to feed light output from the laser back to the laser; an optical splitter that is provided in a path of the feedback waveguide and is operable to output a portion of light propagated in the feedback waveguide to outside; and a first ring resonator that is operable to be optically connected to the feedback waveguide, as well as a reservoir computing system including this laser apparatus.

A reservoir computing system comprising:
- a reservoir including a laser apparatus, wherein the laser apparatus includes
- a laser,
- a feedback waveguide that is operable to feed light output from the laser back to the laser,
- an optical splitter that is provided in a path of the feedback waveguide and is operable to output a portion of light propagated in the feedback waveguide to outside the feedback waveguide, and
