Latest Patents

Häusler holds a patent for a "Method and device for passivation of the resonator end faces of semiconductor lasers based on III-V semiconductor material." This patent describes a method for passivating the resonator end faces, particularly the cleaved edges of semiconductor laser diodes. The process involves high-temperature epitaxy of the quaternary compound semiconductor InGaAsP. An additional passivation layer may be applied in situ to enhance the performance of the InGaAsP. The semiconductor crystal is heated to the required temperature for epitaxy, and to prevent thermal destruction of the contact metal, the metal is deposited only after the cleaving operation and passivation. This innovative method can be applied to the production of high-power laser diodes.
