Self-adjustment of a nonlinear lasing mode to a pumped area in a two-dimensional microcavity [Invited]
Fig. 1. (a) Double-triangle orbits in the quadrupole-deformed cavity. (b) Spatial selective pumping (yellow region) along the upward-pointing triangle orbit (red lines).
Fig. 2. Intensity distributions of the resonant modes for a passive quadrupole-deformed cavity with refractive index 3.3. The modes are four nearly degenerate modes associated with the double-triangle orbits. The double-triangle orbits (red and green lines) are superposed, and the intensities outside the cavity are plotted in log scale. (a) Even–even mode with scaled frequency
Fig. 3. Phase space of the ray dynamics for the quadrupole-deformed cavity. The islands of stability corresponding to the upward-pointing and downward-pointing triangle orbits are indicated by red and green points, respectively. The critical line for total internal reflection is indicated by a line at
