Design of polarization conversion and rotation based ternary logic AND/NAND, OR/NOR, Ex-OR/Ex-NOR gates using ring resonator

The present work describes the polarization conversion and rotation based all-optical ternary logic AND/NAND, OR/NOR and Ex-OR/Ex-NOR gates using pump-probe configuration in a single micro-ring resonator. The ternary logic (0, 1, 2) states of the proposed model are represented by three different polarization states of light such as horizontal polarization, linear polarization at 45° and vertical polarization states of light. We develop a new polarization conversion and rotation technique using micro-ring resonator based all-optical switch that produces desired output states such as logic high, low and intermediate state according to the truth table of the respective gates. The performances of the different logic gates are analyzed by Jones matrix in terms of the Azimuth angle and Ellipticity angle and by Stokes parameter in terms of S1, S2, S3 using INTERCONNECT simulation software. These ternary logic gates emerge as a promising paradigm with the applications in low power photonics, quantum computing, optical computing and nanotechnology.
