Fokussierung von Strahlung
The invention relates to a beam shaping optics which stigmatically focuses the radiation emitted by a point light source in a planar waveguide. Such light sources are available, for example, in the form of particular high-power semiconductor laser diodes, in particular in tapered lasers.
Tapered Lasers for which the invention may be used combine both directivity of a Fabry-Perot-Laser with high performance of broadarea lasers showing large scale integration. The patented technology is capable of correcting optical aberrations, especially spherical aberrations.
