Abstract
Section titled âAbstractâThree-dimensional (3D) fabrication by direct laser writing opens new perspectives in resonator design and laser applications. We fabricated various shapes and sizes of microlasers of nanoscale quality: pyramids, tetrahedra, and 3D plano-concave cavities. The lasing thresholds depend on the resonator shapes and are lower than those of equivalent two-dimensional microlasers. The experimental spectra and the directions of emission may be predicted via a semiclassical analysis using periodic orbits, in good agreement with experiments. The screw angle is a key quantity to characterize a periodic orbit in 3D resonators. In this proceeding, we present different methods to calculate the screw angle in polyhedra, based on the example of the folded diamond periodic orbit in the square pyramid. Preliminary experimental results on the regular tetrahedron are also reported.
