Abstract

We present an erratum regarding the number of space group in our paper.

© 2017 Optical Society of America

We have found that the correct space group of the photonic crystal in our main text [1] is 224 [The incorrect ‘space group 208’ appears at paragraph 2, page 2 and paragraph 1, page 3]. It has inversion symmetry, as can be seen in Fig. 1 with a different origin changing from (0, 0, 0) to (1/4, 1/4, 1/4)a. The results in our paper are still valid. We note that its space group was incorrectly identified as 208, as in [2-3] of liquid crystals.
