The PC L3 nanocavities with different slab thicknesses. The air hole displacements are A = 0.2a, B = 0.025a, and C = 0.2a. (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. Each ‘vertical line’ is actually a Lorentz function with small full-width at half maximum. (b) The quality factor. (c) The mode volume. (d) The ratio of g/κ.
