    • An optical comparator circuit comprises a first stage comprising an optical gate (10) which receives the signals (A and B) applied to the two inputs and produces at its output an N bit s i g n a l with e a c h bit being representative of the logical expression A XOR B for a respective pair of bit s of the words A and B, a second stage which comprises an optical gate (20) having at least two inputs, a first input being connected to the output of the first stage by a n optical connection having a first time delay, and a second input being connected to the output of the first stage through (N-I) further optical connections, each further connection having an associated time delay which is longer than the first time delay, the second stage providing at its output a signal comprising N bits, each bit corresponding to a respective bit of t he signal output from the first stage at that time, and each bit having a first value if all of the inputs to the stage at that time are equal and a second value if and only if the first input differs in value from all of the second inputs, and a third stage which comprises an optical gate (30, 40) having two inputs, the first input being connected to the first input node of the circuit and the second input being connected to the output of the second stage, the output of the third stage comprising an N bit signal with each bit having a first value if the inputs at that time differ and a second value if the inputs at that time are the same, the presence of the second value in the output being indicative of word A being greater than word B.
    • 光学比较器电路包括第一级,其包括光栅(10),其接收施加到两个输入端的信号(A和B),并在其输出端产生一个N位信号,每个位代表逻辑表达式A XOR B 对于字A和B的相应的一对位,包括具有至少两个输入的光栅(20)的第二级,第一输入通过光连接与第一级的输出连接,该光连接具有第一 时间延迟,第二输入通过(NI)另外的光学连接连接到第一级的输出,每个另外的连接具有比第一时间延迟更长的相关时间延迟,第二级在其输出端提供信号 包括N个比特,每个比特对应于当时从第一级输出的信号的相应比特,并且如果所有到该阶段的输入的所有输入相等,则每个比特具有第一值,并且第二 值,当且仅当第一输入的值与所有第二输入不同时,第三级包括具有两个输入的光栅(30,40),第一输入连接到电路的第一输入节点,以及 所述第二输入端连接到所述第二级的输出端,所述第三级的输出包括N位信号,如果所述时间的输入不同,则每个位具有第一值,并且如果当时的输入为第 相同的是,输出中第二个值的存在表示字A大于字B.
