In this paper, microring resonator-based logic gates are discussed that operate on same input and output wavelength. Same input and output wavelength allows the cascaded operation of the developed logic gates and thus can be utilized for developing photonic integrated circuits. Logic operations such as and, or, nor, xor , and xnor are successfully demonstrated. Optical Kerr effect is utilized for operation and structures are numerically simulated using coupled mode equations. Output power levels of around 0.18 and 0.05 W are achieved for high- and low-power logic, respectively. The proposed structures perform well for data rate under 1 Gbps and are analyzed to determine the acceptable input range for high- and low-power logic, respectively. The cascaded operation of proposed logic gates is also demonstrated.
