In this work, we present the design of NOR, OR, AND and NAND optical gates using micro-ring resonator structures. The all-optical gates’ structure thus consists of several micro-ring resonators (MRR) and a constant source of light. MRRs in these designs are utilized as modulators by tuning their coupling wavelength. In this way, under no external disturbances, the rings are uncoupled by default. All gates were constructed through adopting some of the design features of their electronic counterparts. Since power attenuation is one of the major issues, cascaded effect of the gates is also studied and considered in the design. In order to design and simulate the gates such computing tools as MATLAB and Lumerical were employed. Various analyzers were applied to retrieve optical component characteristics. Device fabrication parameters are provided as well for further post-manufacturing tests. The study concludes with suggestions on design improvements and potential application of the all-optical logic gates.
