Paper Abstract

An illustrative, device systems level desirability optimization analysis has been performed for a number of important electrooptic materials that are candidate for use in high-speed guided-wave optical devices. Ferroelectric materials with high and low transition temperatures, cubic crystals, organic crystals, and alloy semiconductors have been considered. The bulk guided-wave phase modulator has been taken as the initial screening device. Performance measures such as electrical power supply constraints and the device's maximum operating speed have been analyzed as a function of system variables that include material properties and electrode architectures. Desirability analysis has been presented as a composite mathematical function that describes two or more independent performance measures in terms of all relevant system variables. This function has been displayed graphically to identify those sets of system variables that jointly optimize the performance measures of greatest interest. The initial screening analysis has ignored propagation loss and less-than-ideal overlap between electrical and optical fields. Potassium niobate, barium titanate, and lithium niobate have been found to be among the more desirable electrooptic materials. The use of dielectric buffer layers, several thousand Angstroms in thickness, has been found necessary to isolate the modulator electrodes from high dielectric constant, high electrooptic strength materials such as potassium niobate. Buffer layers, however, have been found to be generally unnecessary when using the lower permitivity and lower electrooptic strength materials such as lithium niobate.
