Paper Abstract

Light propagation in optical films grown by pulsed laser deposition was studied numerically. We found that the natural curvature of this films introduced during the growing procedure can lead to an increase of the confinement factor of the optical radiation, which increases the pumping efficiency of the planar waveguide lasers. Moreover, the film curvature does not affect significantly the overlap of the pump and the signal fields inside the active layer.
