Abstract
This paper demonstrates the effective applicability of electro-optic effect for the implementation of half adder using Mach–Zehnder interferometers (MZIs). Performance enhancement using electro-optic switch implemented using MZIs based on titanium-diffused lithium niobate (Ti:LiNbO3) functioning as waveguide medium at 1.33 µm wavelength is detailed in the work. The design implemented consists of three MZIs giving optimized operation in terms of low insertion losses, high extinction ratio and low switching voltage. Further, the titanium strip thickness and the arm gap between waveguides of the electrode regions were varied and analysis of the device performance has been done. Mathematical description of the device operation is also included, and the obtained results of MATLAB simulations and beam propagation method applied were compared and verified.
