Dissertation note: Thesis (Ph.D.) - Cairo University - Faculty of Engineering - Department of Mathematics and Physics Summary: Two modified derivative free trust region algorithms have been proposed. The first is an unconstrained trust region (UTR) algorithm, while the other is a constrained trust region (CTR) algorithm. Both algorithms use quadratic surrogate models as a function approximation. The accuracy of the two modified algorithms is measured by applying them to some bench-mark and test functions. The CTR is used to obtain an optimal design for a photonic crystal fiber (PCF) polarization rotator. Further, the UTR algorithm has been employed in the optimization of the PCF dispersion and some practical polarization devices for the (PCFs) and EM-based systems
