The new optoelectronic logic gate is wavelength-independent due in part to interferometric switches as comparators of optical bits and electrical bits. In the processing imprint stage the logic gate is separated into two parts consisting of a single interferometric switch for single bit operation to imprint electrical input data on an optical signal, and the comparator stage, consisting of two parallel interferometric switches wherein input data is superimposed on the optical signals compared with target data in the electrical realm. The comparator stage is the key to simultaneous processing, as all relative timing signals can be sent to it at the same time. With the optoelectronic logic gate, a user can locate and detect real-time streaming input data without needing prior knowledge of the data other than its rate. The setup can be scaled with the inclusion of multiple interferometric switches and multiple mode-locked optical frequencies thus detecting much longer target patterns, faster, in streaming data.
