Abstract

Mach-Zehnder type GaAs elcetro-optic waveguide modulator has been designed in this paper.The modulator. Considered is based on the Mach-Zehnder interferometer configuration, consisting of two Y branch couping rib type waveguides formed in two epitaxial layers on GaAs substrate. The mode theory on waveguides and electo-optic effect of GaAs were utilized to determine the design parameters for the modulator proposed. Effective index method was applied to design the of waveguide supporting a single mode were calculated to achieve the optimized operation of the modulator. Considering interrelationships between many parameters.
