Abstract (Summary)

A perfect amalgam of optics and telecommunications has created many innovations in the field of antenna theory. One such revolution has ameliorated the world of optical communication technology giving rise to the development of array theory and beam steering networks. The reason behind the growing expansion of optical beam steering is due to its applications in radio astronomy, remote sensing and radar, photonic applications, spectroscopy and much more.

Over the years, implementation of optical beam steering has been achieved through several techniques. Recent research reveals that conventional methodologies such as mechanical steering, and parasitic steering have accomplished beam steering; however, the most effective and practical steering technique is a phased array scheme. Consequently, this research demonstrates how to accomplish beam steering through an optical phased array structure of metal and dielectric elements without involving either the electrical components or the physical movement of the source, and array members. The purpose of avoiding electrical components, and the physical movement of hardware elements is to make the steering process simpler and pragmatic. To achieve this purpose of a simple steering process, this project implements the Finite Difference Time Domain (FDTD) method in order to analyze the Electromagnetic (EM) phenomena at optical frequencies. As a result, all the numerical simulations are executed using FDTD software developed by Lumerical. Significantly, FDTD simulation tool determines the time-varying EM field distribution in the designed array model.
