(Color online) (a) Dispersion curves of a PC waveguide and the resonances of the L7 and L11 cavities; the shaded area is the leaky region. A scanning electron microscopy inset shows the L7 cavity. (b) spectra of the L3, L7, and L11 lasers far above threshold. Cavity modes are identified with the calculated profiles.
(Color online) Lasing characteristics of the laser diode. (a) The output power is plotted as a function of the operating current. (b) The values as a function of threshold-normalized current for the shaded region of (a). The insets show the emission spectra at different currents.
(Color online) Lasing characteristics of the L3 laser. The data and the output intensity are plotted as a function of incident power. The spectra taken at 0.6 and are shown in the insets, where parallel lines indicate the standard deviation noise.
(Color online) (a) data of QD PC lasers are compared with the theoretical curves obtained with for L3, for L7, and for L11, respectively. (b) data of the MQW laser are compared with the theoretical curves obtained with .
