Design and modeling of multi-operation bit-manipulator logic circuit using lithium niobate waveguides

Abstract

In this work, a high-performance multioperation bit-manipulator is presented. The presented electro-optical design can perform several bit-manipulations such as bidirectional bit-shifting, bit-rotation, multiply-by-2 and divide-by-2, and sequence designing operation. The technique relies on the electrooptic principle in lithium niobate. Lithium niobate-based waveguides have been used to design Mach–Zehnder interferometer, which is the fundamental optical switching element of the whole model. Extinction ratio, contrast ratio, and insertion loss values computed for the simulated results are 29.16 dB, 29.48 dB, and 0.77 dB, respectively.
