摘      要：An XOR/XNOR optical logic circuit with two cascaded microring resonators and two U-bend waveguides is proposed. The microring resonators are made of electro-optical polymer and modulated through linear electro-optical effect. Two electrical signals are applied to the two microrings, and simultaneous XOR and XNOR operations are demonstrated in two different operating modes. We also use scattering matrix method to analyze the analog output spectra, and find that different inputs like ‘00 and ‘11 can lead to different extinction ratios in output spectra at certain wavelengths, even though their digital outputs are the same.
