Directional Emission from Microlasers with Open Chaotic Resonators

Using topological classical considerations (Poincare maps) the appearance of bow-tie shaped resonances is predicted for certain types of waveguides. The geometry of such waveguides is chosen to yield mixed chaotic dynamics. Then, based on resonance effects, we propose the construction of directional emission microlasers using open chaotic semiconductor resonators of high refractive index.
