Figures

Image of FIG. 1.
FIG. 1.

(Color online) (a) SEM images of fabricated devices for Designs A and B. (b) Normalized Hz field component of the lasing modes for L3, L5, and coupled-cavities.

Image of FIG. 2.
FIG. 2.

(Color online) (a) Lasing spectra of coupled-cavity lasers, insets show CCD camera image of the lasing device and its corresponding simulation results. Simulation of far-field emission patterns for single L3, L5, and coupled-cavity lasers: (b) suspended PhC slab with no substrate and (c) PhC slab suspended 1160 nm above the InP substrate. Dashed white circles indicate 30°, 60°, and 90° from surface normal.

FIG. 3.

(Color online) Design B device measurements: (a) rate equation fitted L-L measurement on log-log scale, circles represent measured data, solid black line is the fit, calculated Fpβ = 1, 0.1, 0.01, and 0.001. L-L curves using the fit data are in green dashed lines. Inset shows a zoom-in at the threshold in linear scale. (b) Measured linewidth, solid line shows the Lorentzian fit. (c) Measured wavelength shift versus effective pump power, solid line is the above-threshold /dW fit.
