Abstract: A solid-state light source with built-in access resistance modulation is described. The light source can include an active region configured to emit electromagnetic radiation during operation of the light source. The active region can be formed at a p-n junction of a p-type side with a p-type contact and a n-type side with a n-type contact. The light source includes a control electrode configured to modulate an access resistance of an access region located on the p-type side and/or an access resistance of an access region located on the n-type side of the active region. The solid-state light source can be implemented in a circuit, which includes a voltage source that supplies a modulation voltage to the control electrode to modulate the access resistance(s).

Abstract: An interface including roughness components for improving the propagation of radiation through the interface is provided. The interface includes a first profiled surface of a first layer comprising a set of large roughness components providing a first variation of the first profiled surface having a first characteristic scale and a second profiled surface of a second layer comprising a set of small roughness components providing a second variation of the second profiled surface having a second characteristic scale. The first characteristic scale is approximately an order of magnitude larger than the second characteristic scale. The surfaces can be bonded together using a bonding material, and a filler material also can be present in the interface.

Abstract: A solution for treating a fluid, such as water, is provided. The solution determines an ultraviolet transparency of a fluid 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.

Abstract: Ultraviolet radiation is directed within an area. Items located within the area and/or one or more conditions of the area are monitored over a period of time. Based on the monitoring, ultraviolet radiation sources are controlled by adjusting a direction, an intensity, a pattern, and/or a spectral power of the ultraviolet radiation generated by the ultraviolet radiation source. Adjustments to the ultraviolet radiation source(s) can correspond to one of a plurality of selectable operating configurations including a storage life preservation operating configuration, a disinfection operating configuration, and an ethylene decomposition operating configuration.
