  • Publication number: 20190237937
    Abstract: A surface emitting laser includes a conductive substrate, a metal bonding layer, a laser structure layer, an epitaxial semiconductor reflection layer, and an electrode layer. The laser structure layer has an epitaxial current-blocking layer having a current opening. Currents are transmitting through the current opening. The epitaxial current-blocking layer is grown by a semiconductor epitaxy process to confine the range of the currents to form electric fields.
    Type: Application

  • Patent number: 10305255
    Abstract: A surface emitting laser includes a conductive substrate, a metal bonding layer, a laser structure layer, an epitaxial semiconductor reflection layer, and an electrode layer. The laser structure layer has an epitaxial current-blocking layer having a current opening. Currents are only transmitting through the current opening. The epitaxial current-blocking layer is grown by a semiconductor epitaxy process to confine the range of the currents to form electric fields.

  • Publication number: 20190031544
    Abstract: Devices are provided herein for the purification of free flowing or semi-free flowing bodies of water by removing impurities, such as nitrates. In one or more implementations, the impurity-removing device includes a cylindrically shaped housing that is open on both ends and defining an inner cavity. A cap is disposed at one opening at one end of the housing, the cap having multiple openings placed through the cap and being sized and shaped to fit the opening at the end of the housing. The impurity-removing device also includes a collection strip on an outer surface of the housing that is colored, sized and shaped to collect heat or energy from the environment, and an impurity-removing medium contained within the inner cavity.

  • Patent number: 8028909
    Abstract: An imaging system with in-field image quality testing and reporting features, includes a housing, and a solid-state imager having an array of image sensors supported by the housing for capturing return light from a target located in a range of working distances from the housing in an image capture mode of operation, and for capturing return light from a test pattern positioned at a predetermined position in the range of working distances in a test mode of operation different from the image capture mode. An electrical signal indicative of the captured return light is generated in each mode. A memory is supported by the housing for storing a test program for testing image quality.
