Résumé
Microlasers are involved in a broad range of devices for numerous research applications. However, the mode structures of three-dimensional microlasers without rotational symmetry are largely unexplored. Previous studies of such cavities revealed lasing modes exclusively localized on periodic orbits in the plane parallel to the substrate, which is to say that the associated momentum vectors are concentrated in the plane. In this paper, we characterize three-dimensional, polymer-based Fabry-Perot (i.e., ribbon-shaped) microcavities and demonstrate that such cavities exhibit modes with momentum vectors out of the substrate plane. These results constitute a proof-of-principle and motivate follow-up studies with more complex three-dimensional geometries.
