1. An optical subassembly comprising:
a housing that defines a central space and first, second, and third channels which extend from the central space;
a laser package affixed to the third channel and comprising a UV-C laser diode chip disposed in the central space and having first and second edges;
a first end section of side-emitting optical fiber retained in the first channel and having a first end face which confronts the first edge; and
a second end section of side-emitting optical fiber retained in the second channel and having a second end face which confronts the second edge.
