    Abstract: A solution for treating a fluid, such as water, is provided. An ultraviolet transparency of a fluid can be determined before or as the fluid enters a disinfection chamber. In the disinfection chamber, the fluid can be irradiated by ultraviolet radiation to harm microorganisms that may be present in the fluid. One or more attributes of the disinfection chamber, fluid flow, and/or ultraviolet radiation can be adjusted based on the transparency to provide more efficient irradiation and/or higher disinfection rates. In addition, various attributes of the disinfection chamber, such as the position of the inlet(s) and outlet(s), the shape of the disinfection chamber, and other attributes of the disinfection chamber can be utilized to create a turbulent flow of the fluid within the disinfection chamber to promote mixing and improve uniform ultraviolet exposure.

    Abstract: A light emitting device having improved light extraction is provided. The light emitting device can be formed by epitaxially growing a light emitting structure on a surface of a substrate. The substrate can be scribed to form a set of angled side surfaces on the substrate. For each angled side surface in the set of angled side surfaces, a surface tangent vector to at least a portion of each angled side surface in the set of angled side surfaces forms an angle between approximately ten and approximately eighty degrees with a negative of a normal vector of the surface of the substrate. The substrate can be cleaned to clean debris from the angled side surfaces.
