摘要

Abstract Plasmonics, often referred as “light on wire”, is an emerging nano-scale technology having the advantages of higher speed computing over the electronic devices and comparatively smaller size than the electro optical devices. With the help of plasmonics, it is possible to transmit data between chips at optical speeds and thus opening the doors towards miniaturization of devices and faster computers. Reflective codes are the self-complementing codes, which are used for communicating with computers. In this work, a novel design of plasmonic 2421 reflective code using plasmonic Mach–Zehnder interferometer has been proposed. As the designed reflective code is plasmonics based, hence it has smaller size, better processing speed, faster switching of light, better optical stability, lesser power consumption than the existing designs of codes. The footprint of the proposed device is only 190 µm × 35 µm with an extinction ratio of 18.23 dB. The performance of the device is theoretically analysed using a numerical analysis technique i.e. finite-difference-time-domain (FDTD) method and then comparing the simulation results of FDTD method with the MATLAB simulation results.
