Latest Patents

Wagner holds a patent for a "Buried double heterostructure laser device." This invention describes a buried double heterostructure laser device that utilizes a wafer of double heterostructure material formed into narrow mesa stripes. A native oxide coating is applied to the side walls of the mesa, and semiconductor material with an index of refraction closely matched to the active region is deposited over the mesa structure. The design achieves vertical carrier and optical confinement through higher bandgap cladding layers, while the native oxide serves as an electrical insulator to confine pumping current to the mesa. This innovative device has demonstrated continuous wave threshold currents at room temperature as low as 55 mA.
