The coupled‐resonator‐induced transparency (CRIT) effect in parallel‐coupled double microring resonators (MRRs) has been widely studied, and various applications based on the CRIT have been demonstrated. As an application of the CRIT, we propose and demonstrate a directed logic circuit that can implement the XOR and XNOR operations. Two electrical signals applied to the two MRRs represent the two operands of the logical operations, and the operational results are represented by the output optical signal. As a proof‐of‐concept, the thermo‐optic modulating scheme is employed with an operational speed of 10 kbps.
