The PC L3 nanocavities with the slab thickness d = 0.6 a and different air hole displacements. Including ‘no displacement’ (denoted as No), ‘A = 0.2a’ (denoted as A), ‘A = 0.2a, B = 0.025a’ (denoted as AB), and ‘A = 0.2a, B = 0.025a, C = 0.2a’ (denoted as ABC). (a) The PLDOS at the center of the PC L3 nanocavities, orientating along the y direction, normalized by the PLDOS in vacuum as ω² / 3π²c³. (b) The quality factor. (c) The mode volume. (d) The ratio of g/κ.
