Image of FIG. 1.
FIG. 1.

(a) Scanning electron microscopy image of a hexagonal-lattice zero-cell-type (H0-type) PhC nanocavity. (b) Three-dimensional FDTD simulated profile of the component for the fundamental mode.

Image of FIG. 2.
FIG. 2.

(a) PL spectrum of QDs measured at 5 K in the unpatterned region. (b) PL spectra of the cavity modes with different lattice constants varying from 290 to 305 nm. The cavities show lasing with QD gain through the nonresonant coupling process. (c) PL spectra for an H0-type PhC nanocavity measured at 80 nW (left, below the threshold) and (right, above the threshold). (d) L-L plot and the linewidth of the cavity mode. The laser threshold is with wetting layer excitation (880 nm).

Image of FIG. 3.
FIG. 3.

(a) L-L plots for an H0-type and an L3-type PhC nanolasers. (b) Laser thresholds of four H0-type (red balls) and four L3-type (blue squares) nanocavities. The pink (280 nW) and light blue (780 nW) broken lines are the averaged values of the respective cavities. H0-type nanocavities have smaller thresholds than L3-type nanocavities.
