Luminescence Originating in an Optical Fiber
Abstract
Recently, there has been considerable research into the development and applications of fiber optic spectroscopic sensors. The large number of recent reviews attest to the widespread interest in this area (1-6). Fiber optics have several advantages over conventional optics; they can easily be miniaturized, and can be used at a remote distance from the laboratory and/or under harsh conditions. Our research group has been active in the area of fiber- optic chemical sensors. In the course of setting up an instrumental system for sensor research, we discovered some unusual luminescence behavior originating in the optical fiber itself. When a pulsed, high-energy, ultraviolet laser beam was coupled into a fused silica fiber, the fiber was seen to glow a bright red color. The color was intense enough to be seen with the naked eye in a well-lit room, and appeared to be uniform along the length of the fiber. We proceeded to study this observed emission. This report summarizes our observations. Optical fibers, Luminescence, Sensors.
