Abstract : The principal objective of this project is to develop a calibrated simulation model which can accurately predict the effects on overall phased array system performance when conventional subsystems are replaced with optically assisted subsystems. The fabrication of high quality integrated optical components requires an accurate prediction of device performance. This is especially true in the fabrication of necessary components such as resonators where commercial software fails to predict the slot mode resonances. This is the first time a spatial mapping of the r-coefficient has been performed. Defects present a clearer picture of the inner workings of optical waveguide crystals such as LiNbO3. This is especially true of crucial quantities such as crosstalk. The effect of proton exchange may play a greater role than previously expected since we found 'cracks' of defects propagating as far as 200 microns into the substrate.
