Characterization of side emitting plastic optical fibers light intensity loss

Abstract: The main role of polymer optical fibers is to transmit light or optical signal to a specified spot. In the case of side emitting plastic optical fibers the light leaks out from their surface. This sidelight can be used for creation of optically active textile structures providing opportunities to highlight people and objects without the need for external exposure. Due to the transmission loss, the intensity of radiation emitted in any direction decays exponentially along the fiber axis with increasing distance… Show more

“…However, the fibers must be treated to ensure that they will emit the guided light from their full length inside the reactor. Křemenáková et al has characterized laterally light emitting, polymeric optical fibers suitable for this purpose. It was shown that increasing the fiber diameter increases the illumination intensity and the attenuation coefficient but also increases the fibers’ rigidity.…”

“…Side emission can be achieved by launching light into the fibre below the critical angle, i.e. non‐guided light escapes after launching . An increased radial light emittance can also be achieved by applying macro‐bends and undulations within a textile manufacturing process .…”

“…This effect can be obtained by the increasing of cladding refractive index or by decreasing of core refractive index. It is possible to use multiple micro-bending of core or cladding; using particulates causes reflection into core/cladding or creation of geometric asymmetry in the core/cladding system [5].…”
