Abstract

We report a simple design of high quality-factor (Q) three-dimensional woodpile photonic crystal (PC) nanocavity with vertically mirror-symmetric structure, which can be realized by changing the stacking order of layers above the cavity layer from ordinary woodpile structures. A Q of 1.7×105 in the mirror-symmetric structure was obtained with a relatively small PC size. This is ∼3.6 times as high as the maximum Q of the same nanocavity embedded in an ordinary woodpile structure of the same PC volume. (© 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
