Abstract
In example implementations, an apparatus includes a bus waveguide, a plurality of optical gates coupled to the bus waveguide and an injection coupler. The bus waveguide receives a plurality of constraint signals. Each optical gate outputs an internal state via a local phase shift when at least one of the plurality of constraint signals has a wavelength that matches a respective resonant wavelength. The injection coupler combines the at least one of the plurality of constraint signals with additional constraint signals that are injected. An error is detected in a bit of a message when an overall phase shift has occurred to the at least one of the plurality of constraint signals causing a power level to exceed a power level threshold of an optical gate when the at least one of the plurality of constraint signals constructively interferes with the additional constraint signals that are injected.
