All-Optical XNOR and XOR Logic Gates Based on Ultra-Compact Multimode Interference Couplers Using Silicon Hybrid Plasmonic Waveguides

Part of the Lecture Notes in Electrical Engineering book series (LNEE,volume 878)

Abstract

We present a new structure based on ultra-compact cascaded multimode interference (CS-MMI) structures using silicon hybrid plasmonic waveguides (HPWG) for all-optical XOR and XNOR logic gates. An ultra-compact footprint of 3 × 16 µm2 can be achieved. We show that the contrast ratios for logic 1 and logic 0 for XOR, XNOR gates are about 20 dB for a ultra-high bandwidth of 70 nm, respectively. A large fabrication tolerance can be achieved by using this structure.
