碩士 === 國立臺灣科技大學 === 電子工程系 === 90 === In this thesis, the topic of research composed of two main approach. First, we derive Electromagnetic propagation matrix by the plane wave theory to simulate and design optical thin-film devices, including edge filters, high reflection coating, and Fabry-Perot narrow-band filters. Second, we apply simulated annealing algorithms to make optimum design for optical thin-film devices. Take two advantages of that, including the ability to solve global optimum and needless to calculate the gradient of target function, to do optical optimum design. We add the number of thin-film layers rather than change the original thin-film layers’refraction-indices and thicknesses. This way makes our research easy to implement. We could make the final merit value close to zero via simulated annealing algorithms. Hence, it improves the question of the large transmittance ripples of the optical thin-film devices. In sum, we prove the accuracy and fitness of the method.
