Latest Patents

Uwe Siegner holds a patent for an "Optically nonlinear semiconductor material and a method for the production thereof." This patent describes how the non-linear optical material characteristics of a semiconductor can be significantly enhanced through specific measures. By doping materials like GaAs with foreign atoms, such as Be, and applying thermal annealing, the response time of the semiconductor can be dramatically reduced. For instance, doping GaAs grown at 300°C with Be to a concentration of 3·10 cm results in a response time reduction from 480 fs to 110 fs. This advancement allows for high absorption modulations and low non-saturable absorption losses, making these materials highly suitable for nonlinear optical applications.
