Integrated optical Mach-Zehnder interferometers in glass

Paul A. Lefebvre, A. Vahid-Shahidi, Jacques Albert, S. Iraj Najafi

Abstract

A potassium ion-exchange process is employed to make integrated optical Mach-Zehnder interferometers in a glass substrate. An extensive study is carried out to determine the contribution of different components of the interferometer in its performance. Propagation properties of Mach-Zehnder interferometers, straight and S-shape waveguides, and Y-junctions are investigated.
