In the analysis of their spatial temporal mode distributions Finite-Difference Time-Domain (FDTD) methods have proved its validity. The output of the FDTD can be seen as the realizations of a multidimensional statistic variable. At the same time, fabrication tolerances induce an added and unavoidable variability in the performance of the microcavity. In this contribution we have analyzed the modes of a defective photonic crystal microcavity. The location, size, and shape of the cylinders configuring the microcavity are modelled as having a normal distribution of their parametric descriptors. A principal component analysis is applied to the output of the FDTD for a population of defective microcavities. The relative importance of the defects is evaluated, along with the changes induced in the spatial temporal distribution of electromagnetic field obtained from the calculation. 0-8194-5835-X 10.1117/12.608709 https://hdl.handle.net/20.500.14352/53480 http://dx.doi.org/10.1117/12.608709 http://proceedings.spiedigitallibrary.org/proceeding.aspx?articleid=865983 http://cisne.sim.ucm.es/record=b3528557~S6*spi Multivariate analysis of photonic crystal microcavities with fabrication defects
