Design and Comparative Analysis between Waveguide Directional Coupler and Multi-mode Interference Coupler for Optical Communication System

Abstract

Recently integrated optical fiber based components plays a important role as optical-MEMS in the optical communication system. In this paper, we optimized design and simulated various kinds of 3dB integrated waveguide beam splitter such as directional coupler (DC), multimode interference (MMI) coupler. These all components optimized for suitable waveguide material such as polymer, Lithium Niobate, silicon etc. Optical directional coupler and multimode interference coupler have been designed, optimized and simulated for optical communication system (OCS).
