Latest Patents

Lauerent holds a patent for a method related to GaAs based lasers. The patent, titled "Method to GaAs based lasers and a GaAs based laser," describes a technique that utilizes dry etching to achieve contamination-free surfaces on materials such as GaAs, GaAlAs, InGaAsP, and InGaAs. This method allows for the creation of nitride layers on various structures of GaAs based lasers. The process involves applying a mask to protect certain areas of the laser surface from dry etching, followed by placing the laser in a vacuum. Dry etching is performed using a selection of chemically reactive gases, inert gases, or a mixture of both. Additionally, a native nitride layer is formed using plasma containing nitrogen, and a protective layer or mirror coating is added to enhance the laser's functionality.
