Abstract
An optical system includes an output waveguide to propagate an optical output signal and a plurality of ring laser systems. Each of the plurality of ring laser systems includes a ring laser to generate a ring laser optical signal and a local waveguide. The ring laser can be optically coupled to the output waveguide to provide a first portion of the ring laser optical signal on the output waveguide as part of the optical output signal, and can be optically coupled to the local waveguide to provide a second portion of the ring laser optical signal on the local waveguide. Each of the plurality of ring laser systems can be to control a phase of the second portion of the ring laser optical signal to provide constructive interference with the ring laser optical signal at an optical coupling of the ring laser and the local waveguide.
