In the topic of the finite-difference time-domain (FDTD) method, we continue to employ the established two-dimensional (2-D) numerical models to simulate and study planar photonic crystal waveguide devices and high-indexcontrast high-density integrated-optic device structures, and further more, we have successfully established the 3-D model. Based on pseudospectral methods, we have also established a 2-D mode solver for analyzing leaky slab waveguides and a highly accurate 3-D solver for 3-D waveguides.application/pdf858926 bytesapplication/pdfzh-TW國立臺灣大學電信工程學研究所光波導光子晶體波導波導元 件有限差分法時域有限差分 法譜方法Optical waveguidesphotonic crystal waveguideswaveguide devicesfinite difference methodfinite difference time domain methodspectral methodreporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/20327/1/932215E002036.pdf
