Nvidia patents backup laser systems for optical data circuits
Nvidia describes a circuit design that uses main laser lights to send data through optical fibers, backed up by secondary lasers. The system uses switches to route light from either the main or backup sources to the output, ensuring a steady signal even if one part fails.
In the filing’s own words
Optical circuit architectures utilizing primary laser light sources and at least one auxiliary laser light source. The primary lasers may be fixed-wavelength lasers and/or comb lasers, and the auxiliary lasers may be fixed-wavelength lasers, tunable-wavelength lasers, and/or comb lasers. In some cases optical switches are utilized along the optical paths in various configurations between the laser inputs and output terminals of the optical paths or between the laser inputs and a transform network.
What exactly they claim (claim 1)
1. A circuit comprising: a plurality of optical paths; one or more primary lasers; a plurality of auxiliary lasers; a single optical switch configured between a primary laser input to each optical path and an output terminal of the optical path; at least one optical switch configured between an auxiliary laser input to each optical path and the output terminal of the optical path; a single optical switch configured along an optical path between each primary laser input and a transform network; and at least one optical switch configured along the optical path between the auxiliary laser input and the transform network.
