Dissertation
Analysis of phased optical waveguide arrays: Application to wavelength division multiplexers
2002
Overview
In this thesis, we consider phased waveguide arrays for wavelength division multi-plexer applications fabricated on InP substrates. A typical phased array component consists of different sections for power splitting, phase shifting and power combination. The analysis of these structures requires both efficient mode solvers and propagation techniques. We have therefore conducted a study of phased waveguide array structures utilizing finite difference procedures for modal analysis and the beam propagation method for the examination of the phase shifts in the waveguide array and in multimode interference sections. Our analytical and numerical procedures include a non-iterative method for the determination of complex propagation constants in planar multilayer waveguide structures and a generalization of a recently proposed one-dimensional asymmetric boundary condition to two-dimensional transverse index profiles. We also examine the possibility of using multimode interference waveguide sections as phase shifters in a phased waveguide array and finally consider an iterative method for optimizing the structure of phased arrays.
