... translating ideas into innovationWelcome to the Ferdinand-Braun-Institut, Leibniz-Institut fuer Hoechstfrequenztechnik! We research cutting-edge technologies in the fields of microwave technology and optoelectronics. For customers in industry and science we provide high-frequency devices and circuits for communication and sensor technology as well as high-power diode lasers for materials processing, laser technology, medical technology and high precision metrology. As a competence centre for III/V-compound semiconductors we operate industry-compatible and flexible clean room laboratories with 2"-4" gas phase epitaxy units and a 2"-4" process line. |
NewsAlGaAsP strain compensation layers in GaAs-based edge emitting diode lasers -
Edge emitting semiconductor diode lasers designed for high output power are preferably realized in the GaAs/AlGaAs material system. FBH successfully managed to optimize the overall strain as well as the strain distribution across complex layer structures by in-situ curvature measurements. Our favored approach to decrease the lattice constant and to lower the compressive strain is to replace part of the arsenic atoms in the AlxGa1‑xAs cladding layers with smaller phosphorus atoms. By monitoring the resulting tensile strain with in-situ measurements, wafer curvature can be significantly reduced. FBH research: 21.05.2013 Rote Diodenlaser -
