Abstract: Example systems and methods of UV disinfection of surfaces and/or air are presented which can utilize multiple peak wavelengths of UV light and utilize feedback control with UV light sensors. Some example systems and methods can facilitate sanitation of spaces which can be occupied by people and/or animals such as an interior room or space of a building or mode of transportation, or even an outdoor gathering space. Additionally, or alternatively, some example systems can include a compartment which is configured to block light exposure to people and/or animals during sanitation and into which objects can be placed for sanitation.

Abstract: An integrated circuit/optoelectronic packaging system (100) which comprises OE and IC components packaged to provide electrical input/output, thermal management, an optical window, and precise passive or mechanical alignment to external optical receivers or transmitters. A transparent insulating substrate having electrical circuitry in a thin silicon layer formed on its top side is positioned between the optical fiber and the optoelectronic device such that an optical path is described between the optoelectronic device and the optical fiber core through the transparent insulating substrate. The optoelectronic devices are mounted on the transparent insulating substrate in a precise positional relationship to guide holes in the substrate. The optical fibers are fixed in an optical fiber connector and are held in a precise positional relationship to guide holes in the connector.

Abstract: An optical-optoelectronic coupling structure comprising a flip-chip optoelectronic/ultrathin silicon-on-sapphire device mounted on a V-groove, optical-fiber-bearing carrier substrate, including light-reflective structures for launching light into the optical fiber core or transmitting light emitted by the optical fiber core to the optoelectronic device. The optical fiber may be immobilized in the V-groove using a curable resin adhesive characterized by a refractive index substantially similar to the refractive index of the optical fiber.

A transparent insulating substrate having electrical circuitry in a thin silicon layer formed on its top side is positioned between the optical fiber and the optoelectronic device such that an optical path is described between the optoelectronic device and the optical fiber core through the transparent insulating substrate. Arrays of fibers may be coupled to arrays of optoelectronic devices through a single transparent substrate. The optoelectronic devices are mounted on the transparent insulating substrate in a precise positional relationship to guide holes in the substrate. The optical fibers are fixed in an optical fiber connector and are held in a precise positional relationship to guide holes in the connector.
