Finite-Element Time-Domain Analysis of 2-D Photonic Crystal Resonant Cavities V. F. Rodríguez-Esquerre, Masanori Koshiba, Fellow, IEEE, and H. E. Hernández-Figueroa, Senior Member, IEEE

An efficient novel time-domainfinite-element ap- proach for the analysis of photonic crystalresonant cavities is here introduced. This approach includes a current source, the full-band scheme, isoparametric triangular elements, and perfectly matched layers. The resonant frequency, quality factor, effective modal area, and field distribution can be obtained in a single simulation. Index Terms—Cavity resonators, finite element, isoparametric elements, photonic crystals(PCs), factor, time domain.
