Optoelectronic semiconducting component for generating and amplifying coherent radiation for laser material processing and other applications of high energy laser radiation

摘要

The component consists of planar waveguide stacks (1,3,6) of active and passive layers with partially diffractive boundary surface structures (2,5). The diffractive structures in at least one boundary surface are formed by symmetrical superimpositions of crossing grid structures with variable grid parameters grid constant, grid depth and ridge curvature.
