The referenced article [Appl. Opt.59, 11112 (202APOPAI0003-693510.1364/AO.412267] has been retracted by the author.A comparator is one of the important combinational logic circuits. An optical comparator was designed and simulated based on photonic crystals. Point and linear defects were also used in the proposed optical comparator. The use of simple defect paths and the absence of ring resonators reduced the complexity of the structure. One of the characteristics of the proposed structure is that it has a very small size, which le
