This paper proposes the design an all-optical 1-bit digital comparator. The comparator structure consists of micro-ring resonators (MRR) paired with a constant light source (COS). MRRs in the comparator design are utilized as modulators by tuning their resonant wavelengths. In this way, under no external disturbances, the rings are uncoupled by default. The proposed 1-bit digital comparator is CMOS-compatible meaning that it can be fabricated using the existing technologies. Also, to reduce the fabrication complexity of the proposed device, thermo-optic modulation is employed as the primary light modulating technique. The 1-bit digital comparator is tested at 0.5 Mbps. The study concludes with suggestions on design improvements and potential application in photonic computing.
