ABSTRACT
A π-conjugated polymer film was fabricated into an asymmetric microlaser resonator having a quadrapole deformation with irregular boundaries and a Q factor of 600. At high excitation intensities above the threshold for lasing, we observed multimode laser emission spectra and directional emission at four different angles. Chaotic ray dynamics explains the observed emission pattern. © 2004 American Institute of Physics.

    A vertical cavity surface emitting laser with saturable absorber can work as a cavity soliton laser. We show that the properties of the system are deeply influenced by the radiative recombination of carriers. The existence of solitons is shown numerically for a choice of parameters suitable to...
