(a) Stylized unperturbed PhC lattice with arrows indicating shift direction. (b) SEM image of a 3/4 lambda shifted cavity. (c) and (d) Lasing mode of the 1/4 and 3/4 lambda shifted cavity, respectively (real part of the magnetic field component perpendicular to the slab shown).
Spectrum for cavities with a shift of 1/4 and 3/4 lambda measured at the lasing threshold power.
LL-curve, linewidth, and peak position for different powers of the lasing modes shown in Fig. 2.
