Wideband, GMR-based reflector is designed employing a novel variant of memetic algorithm with fuzzy logic local search. High quality, single periodic layer reflector with SOI structure is designed with reflectance > 99.50% over 1.35 μm to 1.9 μm spectral band. The proposed optimization/design method is very powerful and able to optimize complex structures with desired optical responses.
