An optical subassembly includes a housing, a laser package, and first and second end sections of side-emitting optical fiber. The housing defines first, second, and third channels which extend from a central space. The laser package is affixed to the third channel and comprises an edge-emitting UV-C laser diode disposed in the central space and having first and second edges. The first end section of side-emitting optical fiber is retained in the first channel and has a first end face which confronts the first edge. The second end section of side-emitting optical fiber is retained in the second channel and has a second end face which confronts the second edge. The housing further defines a fourth channel which extends from the central space. The optical subassembly further includes a transparent window seated in an opening of the fourth channel.

Optical subassembly having side-emitting optical fiber coupled to high-energy UV-C laser diode

High-energy optical disinfection systems inside a commercial airplane using highly efficient, flexible, and durable side-emitting optical fibers optically coupled to high-energy UV-C laser diodes to destroy submicroscopic infectious agents and inactivate microorganisms inside the airplane. With the high-energy UV-C laser diodes optically coupled to the side-emitting optical fibers, which can be easily routed to different areas inside the airplane, the high-energy UV-C laser light emitted from the side of the optical fiber will disinfect the airplane along a wide or long swath continuously without interruption.
