| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In this paper, the topology optimization based on function expansion method is employed to the optimization of the dispersion property and the optimum design of low-dispersion slow-light photonic crystal waveguides (PCWs) is demonstrated. The objective functions to be optimized are determined to get the desired group index and dispersion characteristics. The optimized PCW here have the group index of 81 and wavelength band width of 7.2nm. However the obtained PCW has complicated and find structure. In order to suppress fine structures, we use a smoothing filter in the optimization process and obtain the simplified structure with almost same propagation properties. Using the dispersion property for the obtained structure, the actual pulse propagation is calculated to shown the validity of this design method. |
