Abstract

Methods for predicting the refractive indices of materials are evaluated with respect to the design criteria for composite optical limiters. The efficiency of a nonlinear Christiansen optical limiter is dependent upon refractive index of the individual phases of the composite device and their comparative response characteristics. The overall performance of the structure-property relationships for the linear refractive indices is generally excellent within the training sets; however, the accuracy of an individual case sample is challenged by the low energy case requirements. Outside the general class of materials for which these methods were designed, significant degradation occurs as a result in incomplete parameterizations or compounding errors of imprecise predictions. Accurate predictions of linear and nonlinear refractive indices by TDHF methods are more problematic, yet these techniques demonstrate sensitivity to chemical bonding environments.
